Hello friends, I am a novice in php. Though I create 2 scripts: 1. students registration form 2. search students by Registration Number Our students' Registration Numbers are as follows: nifeA001, nifeA002 & so on... But when someone enter just "nife" or "n" or "A" etc all the students's data is showing. I want that students can search data by entering only Full Registration Number not a Part. I am placing the search.php code below. Please help me out.... ----------------- Search.php ------------------ <?php mysql_connect("localhost", "root", "") or die("could not connect"); mysql_select_db("student") or die("could not connect"); //collect if(isset($_POST['search'])) { $searchq = $_POST['search']; $searchq = preg_replace("#[^0-9a-z]#i", "", $searchq); //here $query = mysql_query("SELECT * FROM user WHERE registration LIKE '%$searchq%'") or die("could not search!"); $count = mysql_num_rows($query); if($count == 0){ $output = 'There was no search results!'; }else{ while($row = mysql_fetch_array($query)) { $fname = $row['firstname']; $lname = $row['surname']; $id = $row['registration']; $output .= '<div> '.$id.' '.$fname.' '.$lname.'</div>'; } } } ?> <html> <head> </head> <body> <form action="form.php" method="post"> <input type="text" name="search" placeholder="search for students.." <input type="submit" value=">>" /> </form> <?php print("$output");?> </body> </html>

I cannot seem to figure this bit out. I'm trying to load data from an xml file depending on what the value of a url parameter is. I have an attribute set in my xml, but cannot seem to figure out how to go about this. I've looked at several examples of getting the attribute so I'm not sure where I am wrong since I haven't come across an example using url parameters to determine what data should be fetched. Here is what I have so far. An example of my xml file. There will be more records of piercing in this file. <piercings> <piercing id="default"> <title>Piercing Not Specified</title> <names>N/A</names> <gauge>0</gauge> <healing>0</healing> <risk>None</risk> <description>You must first choose a specific piercing from the menu to view information.</description> <aftercare>Aftercare tips will be available once you choose a specific piercing from the menu.</aftercare> <avoid>Things you should avoid will be listed once a specific piercing has been chosen.</avoid> <img>http://via.placeholder.com/350/000000/676767?text=Not%20Specified</img> <additionalimgs> <additionalimg>http://via.placeholder.com/350/000000/676767?text=Not%20Specified</additionalimg> </additionalimgs> </piercing> <piercing id="incomplete"> <title>Listing Incomplete</title> <names>N/A</names> <gauge>0</gauge> <healing>0</healing> <risk>None</risk> <description>The listing for this piercing is incomplete. Once completed the data will appear on this page. Please check back later.</description> <aftercare>Aftercare tips will be available once you the listing is complete.</aftercare> <avoid>Things you should avoid will be listed once the listing is complete.</avoid> <img>http://via.placeholder.com/350/000000/676767?text=Incomplete</img> <additionalimgs> <additionalimg>http://via.placeholder.com/350/000000/676767?text=Incomplete</additionalimg> </additionalimgs> </piercing> <piercing id="antieyebrow"> <title>Anti-Eyebrow</title> <names>Anti-Eyebrow, Teardrop</names> <gauge>16</gauge> <healing>6 - 8</healing> <risk>Rejection/Migration, Scarring</risk> <description>The anti-eyebrow piercing is located on the upper side of the cheek bone right below the orbital socket of the eye. This piercing is most commonly pierced using a 16 gauge curved barbell or custom bent jewelry. This piercing may also be referred to as a teardrop piercing.</description> <aftercare>It is recommended with this piercing to clean twice a day using saline solution or antibacterial soap. Do not overclean. Irritation from overcleaning can result in migration of the piercing. </aftercare> <avoid>Using rubbing alchohol as a cleaner. Changing the jewelry for atleast 3 weeks although recommended to wait until the piercing is fully healed. Pools/hot tubs especially those with chemical cleaners in them. Swimming holes, creeks, rivers, etc. due to bacterial exposure risk.</avoid> <img>http://jessetoxik.com/img/display/stock/antieyebrow_default.jpg</img> <additionalimgs> <additionalimg>http://jessetoxik.com/img/thumb/stock/antieyebrow_1.jpg</additionalimg> <additionalimg>http://jessetoxik.com/img/thumb/stock/antieyebrow_2.jpg</additionalimg> <additionalimg>http://jessetoxik.com/img/thumb/stock/antieyebrow_3.jpg</additionalimg> </additionalimgs> </piercing> </piercings> So for this one I am trying to pull all of the data for the piercing with the attribute of id="antieyebrow". Here is what I tried to retrieve that. URL: http://example.com/piercing.php?location=antieyebrow. if (file_exists($_SERVER['DOCUMENT_ROOT'].'/info/piercing/piercings.xml')) { $piercingxml = simplexml_load_file($_SERVER['DOCUMENT_ROOT'].'/info/piercing/piercings.xml'); $location = $_GET['location']; $piercingid = $piercingxml['id']; } else { $piercingxml = simplexml_load_file($_SERVER['DOCUMENT_ROOT'].'/info/piercing/default.xml'); $location = "default"; } And finally to display the data onto the page: echo $piercingxml->$piercingid[$location]->title; So far nothing from the file is being displayed. How do I accomplish this? Any help as to where I went wrong would be greatly appreciated.

Say there is a complex opt in process where people start to enter their data but certain questions stop them where they close out of the page. They already entered their data and I feel there is a way to grab it and post it to mysql even though they do not click submit. How would this be done? A super simple example (proof of concept) or a link to a tutorial would be very useful.

I have an html form that inserts a record into database. I also have a an html edit form that retrieves the data from the database. Normally everything works. But I just noticed that I have an issue if I use double quotes in the form field. It'll insert into the database fine. The problem arises when outputting the variable in the form field. If I echo it outside the form field, it'll show up fine with the double quotes. But inside the field, I only geta partial string. For eg. $variable_input = '5 3/4" Glitter Concealed Platform Pump'; The above will insert to the database. But if I retrieve it in the form field below, it'll return with one number only. <input type="text" name="title" value="5" /> Is there a way to fix the variable output of the wording that includes the double quotes? -
Here's the code that deals with the client side: search.php <?php //testing if data is sent ok echo "<h1>Hello</h1><br>" . $_GET['search']; ?> This is the link I get after sending foo. http://www.family-line.dx.am/Community/index.php?&search=foo Is that mean it was sent, but I'm not processing it correctly? I'm new to the whole AJAX thing.

For eg, say I am retreiving 3 records from database and they look like this. <div class="record"> <h1>Record title 1</h1> <p>Record description</p> <button class="button">send message</button> </div> <div class="record"> <h1>Record title 2</h1> <p>Record description</p> <button class="button">send message</button> </div> <div class="record"> <h1>Record title 3</h1> <p>Record description</p> <button class="button">send message</button> </div> and this is my ajax to load the form. <script> $(document).ready(function(){ $(".button").click(function(){ $(".record").load("form.php .new-form"); }); }); </script> the form looks like this. <form class="new-form"> <textarea name="message" class="message"></textarea> <input type="button" name="submit" class="form-submit" value="Send Message"> </form> That all works. The only problem with that is, it loads the form in EACH record. How can I make it so that the form only loads to the div record from which I am calling from?

Hi, I have a PHP script using the cURL function. This script send the data by a web service. It works often without problem. Sometimes, he sent a double data : same data by two times. I checked the log file this script (by curl_getinfo) on "total_time" When this script works correctly (it send the data only one time) : the total_time is less than 6 second. but when the total_time is more than 7 second, (this is a casual/occasional situation), my script send same data by two times so it is double data! So the web service send the ACK(Acknowledgment) which takes a long time (more than 7 second) and then, the TCP send again same data to a web service. How can I avoid this doubling ? By increasing this time waiting / time limit ? How can I define this time limit for 12 second? Could you help me : Thanks

Folks, I found this piece of code on my notes. Cannot remember where I grabbed it from. It is supposed to fetch a page and grab it's meta details and display them on screen. Question is: What is this error I am getting ?

I'm writing a PHP-based API around some data that is updated as frequently as once a minute, or as infrequently as once every 15 minutes. I'd like to have a cron job push alerts to end users when certain criteria is met (e.g. data goes above a certain threshold), but because my data changes so rapidly and is prone to wild fluctuations, I'm not entirely sure how to approach this. For reference, users can include, for example, people who have downloaded my Pebble smartwatch app, or my upcoming mobile phone app. The data that I'm most interested in (which, if you're interested, is from the ACE spacecraft, and is used to help people view the northern or southern lights) changes every fifteen minutes, and the Kp index it provides is used as a (arguably) good indicator of how likely you are to see an aurora. Values under 5 are usually of no interest to most, anything above 5 (up to 9) are worth getting an alert about. These values can fluctuate, so if a Kp 5 storm is expected, it can hit 6, then dip to 4, then back to 5 and so forth. This is due to the particles ejected from the sun not being a nice, even "wave". I've personally witnessed nights where Kp goes up, then sits low for a while, so you head home, only to find that 10 minutes later it picked up again. Aaanyway, back to my story, I'd like to find a way to alert users about these values when they're of interest, but without bombarding them with notifications, or missing too many events. Here's the various options I've considered: Send an alert every 15 minutes (too often, too annoying, not 'smart') Send an alert every 15 minutes, but only if the value has increased, then "reset" the check after a period of time (better, but what if it hits 7, then dips to 4 for 45 minutes, then hits 6.99? You'd miss out on an alert!) Find a way to check if the user has dismissed the notification and don't re-send it to them for an hour (not feasible, as Pebble's UX doesn't really allow for that, not to mention iOS doesn't have a way to notify your app when an alert has been dismissed) Some kind of data check, where if a value has remained high for longer than 30 minutes, it's alert-worthy and one gets sent out (but you'd miss out on stuff if the value is high for 29 minutes)And riding on the back of that, if the value remains stable, prime the alert. If it increases after it's primed, send the message. I'm more than happy to do some reading and learning. I just didn't exactly know what to search for, as I'm not dealing with something like storage space (where you can send an email if it hits < 20%, and it's unlikely that the storage will fluctuate between 20% and 21%, causing repeated messages) or rare events like CPU usage that you can alert if it stays high for longer than x many minutes

I have a table like this. investment_id | investor_id | deposit | Date | Status I will be depositing funds into this table. For eg. If I am paying out 1000 investors at a time, 1000 rows will be added to this table. I might do this 100 times a day. That's 100,000 rows added in a day. Each deposit I do will be unique, even though it might be going to the same person multiple times. This could end up with million of rows. I am wondering if this is the correct way to do this or is there a better method?
