I am doing an image gallery. I am debating whether to cycle through my image directory to output html or to create an xml file and cycle through that outputting html. Which would be more efficient?

Hi guys. I have dabbled in PHP for a while. Mainly PHP parsing XML and outputting HTML. I have been learning on an "as needed" basis by reading documentation on php.net, but I would like to get a really good overview of PHP and MYSQL. I also have a large project looming. This project would be creating a reservation system and calendar. Do any of you have a suggestion on the books you have found especially useful, particularly, on PHP with MYSQL databases.

Sorry i did look at the manual. This was the example given thats why i was going about it the way i was. $filename = 'somefile.txt'; if (file_exists($filename)) { echo "$filename was last modified: " . date ("F d Y H:i:s.", filemtime($filename)); } This worked perfectly thank you guys. $date1 = date (filemtime($folder.$filename));

Hello. I want an xml document to update every five minutes. I want to check the documents last modified against the the value of time(). but i cant seem to get it formatted properly. What ( string $format , ) do i use to return an integer formatted like the integer returned by time()? Or i am i going about this all wrong? date (" ???string $format??? ", getlastmod($folder.$filename)) Thanks in advance guys

Hello, I have a project that is a little out of my scope. I need a product gallery and a CMS for it. Like a shopping cart only with no checkout. I can do this with Flash and mysql, or flash and xml, but SEO is important for my client. Does anyone know of writen script for sale, or would anyone be interested in writing it. I would do all the "skin" for it. I would provide styles and layout, I would just need someone to code it up. I attached a pdf that describes further what I need. Here is a link to my test site so far, it is just a home page: http://www.mattpaxton.com/testsDelete/woodheat/ [attachment deleted by admin]

Yup exactly what i was looking for. TNX a lot. My original code worked but i am always looking for better ways to do things.

Hi all. O.K. i have a sorta goofy block of code here. I know there is a much better way to do this. So i was just looking for a little insight on looping through an array with PHP. here is the code i have. $error_str = ''; if($_POST["email"]) { $email = $_POST["email"]; }else{ $error_str .= "failed to post email"; } if($_POST["info"]) { $info = $_POST["info"]; }else{ $error_str .= "\r\nfailed to post info"; } if($_POST["imagepath"]) { $imagepath = $_POST["imagepath"]; }else{ $error_str .= "\r\nfailed to post image path"; } Now you can see what i am trying to accomplish. Seems to me like a looping through an array would be much cooler. In AS it looks like this var myArray = [item1, item2, item3]; var results:String = ""; for(var i : Number = 0; i < myArray.length; i++) { if(myArray[i] != undefined) { results += "\narray item" + i + " = " + myArray[i]; //this would output something like array item 1 = (whatever the value was) }else{ results += "\narray item" + i + " = undefined"; } } trace(results); /* the above trace would look something like: array item 1 = dog; array item 2 = undefined; array item 3 = cat; */ Can anyone show me how i would properly form a similar loop in php. Or tell me i am all wrong and __________ is the way i should accomplish something like this. Thanks in advance guys.

I think you are exactly right. i have been digging and that is all i can come up with. How would i change the group to allow ftp changes (when executing the creation of the file)?

Hi guys, i am having trouble with permissions after I make a directory. It makes my directory then writes my .xml file to it exactly how i would like it to, but then when i ftp in i cannot delete that directory. I am on a linux server. Does anyone have any insight for me? I am making a new directory and writing an xml file to it, like so <?php $var1 = $_POST["stringXML"]; $varrandom = $_POST["randomString"]; $folder = "./pending/$varrandom/"; if(!is_dir($folder)) mkdir($folder, 0777); $mode = file_exists($folder.'pending.xml')?'a':'w'; $fp = fopen($folder.'pending.xml',$mode); fwrite($fp, "$var1"); fwrite($fp, "\r\n\r\n"); fclose($fp); ?> Thanks in advance

Hey guys i have a 2 part question. I need to copy an xml file from a remote domain to my own domain, to display an RSS feed. I have php doing this. Well, the first part of my question if i have PHP do this every time the page is requested, i think it would increase load time + processor usage, and i would imagine that if i have 10,000 people going to the page at once it could create all kinds of errors, right? Could i write a conditional statement that would only copy the file if it hasn't been modified in more then an hour, if so how? Or is there a better way to do this? Or is having it write everytime the page is requested be ok. Your advice + help is greatly appreciated.

neil.johnson: ignorance (answer to both questions). I am trying to get a hold on how sessions work. i have been reading on it, but it hasn't clicked yet. So i don not need to commit the session with session_write_close? thanks redarrow!

Can i access and change session data after i commit the session? If so how. I want to keep the same session i dont want to destroy and write over it. i just want to add values. So for example i have: session_start(); $_SESSION['blah1'] = "whatever"; $_SESSION['blah2'] = "i love my dog"; session_write_close(); a few pages later i want to change that data but i need to keep the same session id. So for example if (!session_id()) { if (isset($_GET['session_id'])) { session_id($_GET['session_id']); $_SESSION['blah1'] = "new info"; $_SESSION['blah2'] = "i love my dog"; session_write_close(); } session_start(); $_SESSION['blah1'] = "whatever"; $_SESSION['blah2'] = "i love my dog"; session_write_close(); } well, if i remove all my session_write_close() it works in FF, but without session_write_close() the session does not function properly in IE. With the session_write_close() i cannot alter the session data in IE. Both methods work in FF. Any advise would be greatly appreciated. i am stuck here. Thanks in advance, Matt

Yup, same domain. The script i run just doesn't preserve any session data.

I have a very simple session. When i run an external script the session id changes. Has anyone else had this problem? I need to run the script without refreshing the page. Is there a way to have my external script access my session data? if (session_id()) { echo "session has started."; $_SESSION['sessid'] = session_id(); echo $_SESSION['sessid']; } else { $time = time(); $date = $today = date("Ymd"); $id = $time + $date; session_id($id); $_SESSION['sessid'] = session_id(); echo $_SESSION['sessid']; } external script <?php session_start(); echo session_id(); echo $_SESSION['sessid']; ?>

I don't know if i need large amounts of tested code. I really need a shove in the direction of fixing what i have. i am on the verge of having it. Like i said all i need is to pass 1 piece of info via session data. Not even an array of info. 1 string.

db is usually ideal, but i am not skilled in those areas. i am a flash developer, with html and css skills. Also this is really a very small app. it is just for people to submit their resumes to our HR department. I had that all worked out except every week i had to log in and download the resmes for the manager. ( It is corporate policy that i cannot give her FTP credentials. ) So i thought if i could pass just one variable via sessions to 3 scripts it would solve this problem. It would too, only i loose the variable on the very last step of the process. Can anyone offer any insight on my script or a simple workaround?

tnx for looking man I call the scripts one at a time from a flash object. Also the $_POST vars u see being posted come from the flash object as well. All that information is being transfered from flash o.k. Here is the order of things 1: open page 1 2: then the user chooses to upload a file. It writes the file to the server. 3: The user hits submit within my flash object and it calls for the third php script to send an email with a link to the file they uploaded. Everything goes smooth except the link that comes through in the email. The reason i think it is a scope thisg is because it writes the file to the server and names it what i want With this snippet. if (file_exists($filename)) { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$_SESSION['mypath']); chmod("./files/".$_SESSION['mypath'], 0777); All i need to do is preserve that value $_SESSION['mypath'], so that i can refer to it in the email script.

i am trying to pass session data Between scripts w/o refreshing the browser window. I asked for help on this yesterday, but i was beyond help then. i am a lot closer now. I think i am off on the scope of my vars or something. All my scripts work they just are not correctly passing my session data around. Or maybe i do have to refresh my browser window. i dont know. I really apreachiate ANY help, direction, or explaination of why i am so dumb. Tnx in advance My initial page is <?php session_start(); error_reporting(E_ALL); if (isset($_SESSION['mypath'])){ echo "set to"; echo $_SESSION['mypath']; }else{ setit(); } function setit() { echo "settin it up "; unset($mypath); session_unregister("mypath"); $mypath = 'whatever'; echo "$mypath var is now set to = " . $mypath; $_SESSION['mypath'] = $mypath; echo "the session data = "; echo $_SESSION['mypath']; if ( !($_SESSION['mypath'] === $mypath) ) $_SESSION['mypath'] = $mypath; echo "last time = "; echo $_SESSION['mypath']; } ?> This above page calls this script first, i upload a file and write it to my server. _SESSION['mypath'] That all works. i also reset the <?php session_start(); error_reporting(E_ALL); echo "last time = "; echo $_SESSION['mypath']; function goaway() { unset($mypath); session_unregister("mypath"); echo "path cleared = "; } goaway(); if(!is_dir("./files")) mkdir("./files/", 0755); //move the uploaded file $replaceArr = array(" ", "#","!", "*", "^", "+"); $name = str_replace($replaceArr, "_", $_FILES['Filedata']['name']); $filename = "./files/".$name; makemyvar(); function makemyvar() { srand(time()); $random = (rand()%9999); $ext = substr(strrchr($name, "."), 0); $name2 = str_replace($ext,'',$name); $arandomname = $name2.$random.$ext; $mypath = $arandomname; $_SESSION['mypath'] = $mypath; echo "session path = "; echo $_SESSION['mypath']; } if (file_exists($filename)) { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$_SESSION['mypath']); chmod("./files/".$_SESSION['mypath'], 0777); }else if( !($_SESSION['mypath'] === $mypath) ){ $_SESSION['mypath'] = $mypath; echo "last time = "; echo $_SESSION['mypath']; } else { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$name); chmod("./files/".$name, 0777); //$mypath = $name; //$_SESSION['mypath'] = $mypath; } ?> next i call this script This script works it just doesn't correctly pass my session var. session_start(); error_reporting(E_ALL); //echo $_SESSION['mypath']; $sendTo = "[email protected]"; $subject = "RESUME SUBMISSION (applicant)"; $headers = 'From:' . $_POST["email"] .

I see. That was a bit of code that i found on a forum from someone with a similar paroblem. I would think it should work is i removed that entirely right? Cause don't i define $_SESSION['theresumename'] with this code? $replaceArr = array(" ", "#","!", "*", "^", "+"); $name = str_replace($replaceArr, "_", $_FILES['Filedata']['name']); $filename = "./files/".$name; srand(time()); $random = (rand()%9999); $ext = substr(strrchr($name, "."), 0); $name2 = str_replace($ext,'',$name); $arandomname = $name2.$random.$ext; $nizame = $arandomname; $_SESSION['theresumename'] = $nizame; echo $_SESSION['theresumename']; or should i change the bit of code you are refering to, to this: if ( !($_SESSION['theresumename'] === $nizame) ) $_SESSION['theresumename'] = $nizame; echo $_SESSION['theresumename']; I am sorry i am so confused. I think i understand this less now then i did 10 hours ago.

Thanks for your help man. It has to be Defined because my if statement (on page 2) writes the file to the server if (file_exists($filename)) { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$_SESSION['theresumename']); chmod("./files/".$_SESSION['theresumename'], 0777); You know a lot more then I but this bit of code from page to is what names the file that the above code writes to the server it starts with the file that is selected from when the user browses and selects a file to upload: $_FILES['Filedata']['name'] The file name is posted from Flash. i know that part is working because it writes the file to my server with the proper file name. //move the uploaded file $replaceArr = array(" ", "#","!", "*", "^", "+"); $name = str_replace($replaceArr, "_", $_FILES['Filedata']['name']); $filename = "./files/".$name; srand(time()); $random = (rand()%9999); $ext = substr(strrchr($name, "."), 0); $name2 = str_replace($ext,'',$name); $arandomname = $name2.$random.$ext; $nizame = $arandomname; $_SESSION['theresumename'] = $nizame; echo $_SESSION['theresumename'];

The initial page: <?php session_start(); error_reporting(E_ALL); if (session_id()) { }else{ $time = time(); $date = $today = date("Ymd"); $id = $time + $date; session_id($id); print session_id(); echo "time = $time\r\n"; echo "date = $date\r\n"; $_SESSION['theresumename'] = "page opener"; echo $_SESSION['theresumename']; } ?> The first script i run The $_SESSION['theresumename'] is set under the comment //move the uploaded file [/code] <?php session_start(); error_reporting(E_ALL); //create the directory if(!is_dir("./files")) mkdir("./files/", 0755); //move the uploaded file $replaceArr = array(" ", "#","!", "*", "^", "+"); $name = str_replace($replaceArr, "_", $_FILES['Filedata']['name']); $filename = "./files/".$name; srand(time()); $random = (rand()%9999); $ext = substr(strrchr($name, "."), 0); $name2 = str_replace($ext,'',$name); $arandomname = $name2.$random.$ext; $nizame = $arandomname; $_SESSION['theresumename'] = $nizame; echo $_SESSION['theresumename']; if (file_exists($filename)) { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$_SESSION['theresumename']); chmod("./files/".$_SESSION['theresumename'], 0777); }else { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$name); chmod("./files/".$name, 0777); } if ( !($_SESSION['theresumename'] === $theresumename) ) $_SESSION['theresumename'] = $theresumename; echo $_SESSION['theresumename']; ?> [/code] The second script i run <?php session_start(); error_reporting(E_ALL); $sendTo = "[email protected]"; $subject = "RESUME SUBMISSION (applicant)"; $headers = 'From:' . $_POST["email"] .

Tnx guys good catch. Well, now i am at where i was this mprning. It is passing the session data but it changes from what it should be to a random number. Not sure why. This script will successfully writes the file to my server and will name it like this "filename0000.jpg" the zeros being a random #; but when i reference the var $_SESSION['theresumename'] in the next script it returns just a random 4 digit number, and not the same random 4 digit. <?php session_start(); error_reporting(E_ALL); //create the directory if(!is_dir("./files")) mkdir("./files/", 0755); //move the uploaded file $replaceArr = array(" ", "#","!", "*", "^", "+"); $name = str_replace($replaceArr, "_", $_FILES['Filedata']['name']); $filename = "./files/".$name; srand(time()); $random = (rand()%9999); $ext = substr(strrchr($name, "."), 0); $name2 = str_replace($ext,'',$name); $arandomname = $name2.$random.$ext; $nizame = $arandomname; $_SESSION['theresumename'] = $nizame; echo $_SESSION['theresumename']; if (file_exists($filename)) { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$_SESSION['theresumename']); chmod("./files/".$_SESSION['theresumename'], 0777); }else { move_uploaded_file($_FILES['Filedata']['tmp_name'], "./files/".$name); chmod("./files/".$name, 0777); } if ( !($_SESSION['theresumename'] === $theresumename) ) $_SESSION['theresumename'] = $theresumename; echo $_SESSION['theresumename']; ?>

Sorry i forgot to add that i do have session_start(); on the second script

ok i am stumped. I have a php page. This page calls 2 scripts w/o refreshing the page. <?php if (session_id()) { $_SESSION['theresumename'] = "yet to be defined"; }else{ session_start(); $time = time(); $date = $today = date("Ymd"); $id = $time + $date; session_id($id); print session_id(); $_SESSION['theresumename'] = "session just started"; echo $_SESSION['theresumename']; } ?> then when the user hits an upload button it successfully runs this script w/o refreshing that page if(!is_dir("./files")) mkdir("./files/", 0755); //move the uploaded file $replaceArr = array(" ", "#","!", "*", "^", "+"); $name = str_replace($replaceArr, "_", $_FILES['Filedata']['name']); $filename = "./files/".$name; srand(time()); $random = (rand()%9999); $ext = substr(strrchr($name, "."), 0); $name2 = str_replace($ext,'',$name); $arandomname = $name2.$random.$ext; $nizame = $arandomname; $_SESSION['theresumename'] = $nizame; EVERYTHING TO THIS POINT WORKS, then when the user hits submit it runs an email script. All the email script works accept for the one session variable. i don't understand. session_start(); if(isset($_SESSION['theresumename'])){ }else{ $_SESSION['theresumename'] = 'was not set'; } Thank you in advance. i have been trying to pass this one variable since 9 in the AM. I am at a loss.
