  1. I asked this question before and I did receive the answer I was looking for. But now I realize something. It only works for the first result. Let me explain. I am using this API. https://block.io/api/simple/php $get_address = $block_io->get_transactions(array('type' => 'received', 'addresses' => $my_wallet)); $api_amount = $get_address->data->txs[0]->amounts_received[0]->amount; $api_recp = $get_address->data->txs[0]->amounts_received[0]->recipient; $api_trans_id = $get_address->data->txs[0]->txid; $api_sender_id = $get_address->data->txs[0]->senders; These are variables above i am using to check if something is true or not. For eg. The form below. I want to check if the $api_trans_id matches the the post id I submit below. if($api_trans_id == $_POST['trans-id']) { echo 'Success'; } else { echo 'Fail.'; } <form action="" method="post"> <input type="text" name="trans-id" value="" maxlength="1084" /> <input type="submit" name="submit" value="Submit" /> </form> The above works if the first result in the json array below has the same post id or else it fails. I want to loop through ALL the json arrays and try to match the post id($_POST['trans-id']). Below are the 3 array results to give you an example. The first txid is "41d9afcc73da63c45674088411460116cfefe324cc7a6f5fcb267d9f584adf73". If I submit this same id as the post id in the form, it'll be success full. But if I use the 2nd or 3rd txid below, it will fail. So how can I change this "$api_trans_id = $get_address->data->txs[0]->txid;" so that it looks for all three txid instead of only the first one? { "status" : "success", "data" : { "network" : "BTC", "txs" : [ { "txid" : "41d9afcc73da63c45674088411460116cfefe324cc7a6f5fcb267d9f584adf73", "from_green_address" : false, "time" : 1496877627, "confirmations" : 3080, "amounts_received" : [ { "recipient" : "1QFaAYB4r8sk7MG3beb7yY4R21t9JrnMwK", "amount" : "0.00200000" } ], "senders" : [ "2EqvPUTwjUuon6c2a6YxBreJtBkkZD5fsp" ], "confidence" : 1.0, "propagated_by_nodes" : null }, { "txid" : "2f72d4dd97234937ddf6e8174b17a9a421ba35bbfb6fa40cfeb6ac92db6ce032", "from_green_address" : false, "time" : 1491675979, "confirmations" : 12338, "amounts_received" : [ { "recipient" : "1QFaAYB4r8sk7MG3beb7yY4R21t9JrnMwK", "amount" : "0.00010000" } ], "senders" : [ "3L98MQZKvwNo21fFpY7RJ9HYfYdv62XpYz" ], "confidence" : 1.0, "propagated_by_nodes" : null }, { "txid" : "fce58f0cb1d32c1ed7c27825c41753ce98323771bd931f0a0f99b6294d9ee642", "from_green_address" : false, "time" : 1491672301, "confirmations" : 12341, "amounts_received" : [ { "recipient" : "1QFaAYB4r8sk7MG3beb7yY4R21t9JrnMwK", "amount" : "0.00010000" } ], "senders" : [ "4L98MQZKvwNo21fFpY7RJ9HYfYdv62XpYz" ], "confidence" : 1.0, "propagated_by_nodes" : null }, ] } }
  2. Hey! I want to create a website that can test your counting pace. I’ll make colored, square div that change color after 10 to 30 seconds when you hover over it, and then you’ll type down how long you think it took in a form to check if you’re right. My solution to do this is to create the PHP variable $time = rand(10,30), and in CSS get the div:hover transition-delay to be $time. Then, after the form, I need the same variable for if($_POST[timeguess] = $time) {echo “Correct!”}. I have no idea how to access the same variable in both the CSS and HTML, so I hope some of you can help me out! Thanks

    Open PDF File from Variable

    Alright I am so close but can not figure this out, thanks in advance for any help. So what I am trying to do is take the input variables from a form and have them load a specific PDF . <html> <body> <?php if( $_GET["startpoint"] || $_GET["endpoint"]) { $a = $_GET["startpoint"]; $b = $_GET["endpoint"]; echo "Your Startpoint is:". $_GET["startpoint"]. "<br />"; echo "Your Endpoint is: ". $_GET["endpoint"]. "<br />"; echo $a,$b,".pdf"; } ?> </body> </html> This is what I have and it works to display what the two points are what the final pdf file should be. The final echo generates the PDF name echo $a,$b,".pdf"; How can I get it to load a file using this as a variable or the name it generates, thanks.

  6. Hello so I have a simple code here that will check if a random number already exists in the database and will generate a new one: $rand = mt_rand(100000, 999999); $sid = array( ":sponsorID" => $rand ); $accounts = $db->select("accounts", "sponsorID = :sponsorID", $sid) while(count($accounts) > 0) { $newNum = mt_rand(100000, 999999); } What I wanted to do is to echo out $newNum. When I echo it out I get undefined index of that variable. How can I solve this?

  8. Folks, Q1. A function parameter that takes in a constant, can it always take in a variable, unless it needs a handle ? While going through the Explode function tutorial, I did not come across anything that states the 3rd parameter (explode limit) in the Explode function has to be a string or a constant. Like so: <?php //Tutorial: http://www.tizag.com/phpT/php-string-explode.php echo "Script 1"; //Using a Constant as 3rd parameter in the Explode function. Using FOR function. $phrase = "Please don't blow me to pieces."; $words = explode(" ", $phrase); print_r($words); for($i = 0; $i < count($words); $i++){ echo "Piece $i = $words[$i] <br />"; } $explode_limit = 4; $words = explode(" ", $phrase, 4); for($i = 0; $i < count($words); $i++){ echo "Limited Piece $i = $words[$i] <br />"; } print_r ($words); ?>
  9. Say I have the following. record_id | record_name ----------------------------------- 1 one 2 two 3 three 3 three 3 three 4 four 5 five 5 five I want to search through through the table and find all the records. If there are multiple records with same id, I want to combine them into 1 variable and use that. So in the above example, I have 3 threes and 2 fives. I want to combine them so that I only get 1 three and 1 five. How can that be done? A normal query looks like this. $get_records = $db->prepare("SELECT * FROM records"); $get_records->execute(); $result_records = $get_records->fetchAll(PDO::FETCH_ASSOC); if(count($result_records) > 0) { foreach($result_records as $row) { $record_id = $row['record_id']; $record_name = $row['record_name']; } }
  10. Hi All, couldn't seem to figure how to pass data from page 2 to page 1. On page 2 I have this code block: # if the form has been posted if ($_SERVER["REQUEST_METHOD"] == "POST") { # check for empty fields if (!empty(trim(($_POST['name'] == '')))) { $nameErr = "<span class=\"error\">Name is required</span>"; } if (!empty(trim(($_POST['email'] == '')))) { $emailErr = "<span class=\"error\">Email is required</span>"; } # if all is fine, then add data to the database else { $sql = 'INSERT INTO author SET name = :name, email = :email'; $query = $dbConnection -> prepare($sql); $query -> bindValue(':name', $_POST["name"]); $query -> bindValue(':email', $_POST["email"]); $query -> execute(); $message = 'done'; header('Location: index.php'); } } The variable $message I wanted to pass to page 1, where I have this in: <?php if(isset($_POST['message'])) { echo $_POST['message']; } ?> I can't seem to figure out the problem? Any tips? Thanks

  14. Hi, I want to set a variable based on the contents of another variable - I think I've see CASE used for this before but not entirely sure. Basically I'm trying to tidy this up: if ($var1 = "1") { $var2 = "a" } if ($var1 = "2" ) { $var2 = "b" } if ($var1 = "3") { $var2 = "c" } Any help appreciated. Thanks.
  15. I have a simple web page with 2 buttons that change an icon to red or green based on which button is pressed. When the button is pressed, the variable is stored in a text file, and then recalled to display the proper color icon. (When "Power On" is pressed, the icon turns red, and when "Power Off" is pressed, it turns green.) The problem I have is this: When the page is first loaded, the graphic is blank, until a button is pressed, and then the icon displays properly. The text file with the stored variable is always available on the server, but I cant figure out why the page isnt working properly. I know my webpage is probably full of other problems, but I am a real noob, trying to create my home automation webpage... If you are wondering why I am storing the variable in a text file, it was my way of saving this variable, so that another user could open the same webpage at another time, on another computer, and be able to see the correct status icon. if there is a better way (without Java), please let me know!

I have the following three links in same page. http://localhost/folder/file.php?x=link1 http://localhost/folder/file.php?x=link2 http://localhost/folder/file.php?x=link3 i want to show URLs as they are... link1 is to include a file named "x.php" link2 is to include a file named "y.php" link3 is to include a file named "z.php" Can it be done in php only? PS: its not about creating hash ids. and i want to do it without any sql db connection.
  17. I've got a function in my WordPress functions file that sends a Word doc based on what venue the ordered product is from. However I also need to be able to paste variables such as the customer name and others onto the specified word document. It also needs to be in specific places. How can I go about doing this? Please let me know if you have any idea or don't understand me! Thanks!
  18. I have a register form where a user enters a full name, email and password. I do not want to give them the option of choosing their own "username"; rather I want to automatically create the username from their "full name". So far I can create the username by removing space and symbols from full name. Like this. $fullname = trim($_GET['fullname']); $username = preg_replace('/\s+/', '', $fullname); Looking at that, John Smith would become "johnsmith". Since there could be dozens of people with the name "john smith", I was thinking of assigning unique number to each of them. Like this "johnsmith1", "johnsmith2", "johnsmith3"..etc. How would you say I go on incrementing the username like that?
  19. I've been baffled by this for 2 days now and cannot figure it out after exhaustive searches. I'd like to think I'm doing this correctly, but cannot get it to work. I'm trying to use a variable within a query WHERE statement, and it shows 0 results. If I directly hardcode the text instead of using the variable, it works. The variable is pulling from a $_GET, and if I echo that variable, it is showing the correct text. Here's my code: $Domain = $_GET['Domain']; $result = mysql_query(SELECT Code, Title, Domain, Status FROM tablename WHERE Domain="$Domain" ORDER BY Code'); If I swap out "$Domain" for direct text, like "ABC", it works. I have tried swapping out the quotes and single quotes throughout the statement, removing the quotes around $Domain, concatenating the statement separately....all yield erros or the same result. And as stated, if I echo $Domain, it shows "ABC" (or whatever it's supposed to show), so i know it's pulling correctly from the $_GET. Anyone know what I'm doing wrong?
  20. I have a mysql field that I want to store a php variable in and then retrieve it. Example: Color table has the field named colorBackground with the value of #FF0000 CSS table has the field named cssBackground with the value of .background { background-color: #444444; } What I want to do is make Color/colorBackground a variable {{$backgroundcolor = rsColor['colorBackground'] Then I want to change the CSS/cssBackground value to .background { background-color:$backgroundcolor; } Creating the $backgroundcolor works fine. I'm just not sure how to put the $backgroundcolor in my CSS/cssBackground field.
  21. Php Gurus, I have been doing guess work all this time. But not any more. Just gonna ask. Look at the following code: Concentrate on line 5. It is obvious the "$colors" represent the variable name of the whole array thing (or "column" or "row" in MS Excell terminology). But what does the "$value" represent ? Each array's values (or "cell" value in MS Excell terminology) ? So, the value of the variable $value changes on each loop. Right ? From "Red" to "Orange" at the end. Correct ? Example: 1st loop: $value = Red; 2nd loop: $value = Green; And so on. Correct ? <?php $colors = array("Red", "Green", "Blue", "Yellow", "Orange"); // Loop through colors array foreach($colors as $value){ echo $value . "<br>"; } ?>

    external variable for url

    Hi all, So im trying to improve on my PHP as my knowledge isn't that great. lets say for argument sake my ip is: 192.168.0.1 im trying to set a external variable to set this as the url. so on each page i use, for each link instead of typing out the ip address i can simply type: <a href="{url}/index.php">Home</a> and then if it is possible, to do something like this: <link rel="stylesheet" href="{url}/main.css" type="text/css"> all in one file so in my php pages i can simple include 1 php file and it will have all of the relevant stylesheets ect linked to it.
  23. I'm new to php and i have a html form with 2 forms and 2 submit buttons, 1 of the forms is solely for uploading an image i downloaded the php script as i don't understand the code well enough to write it myself. The second form asks for your name and email then when you click submit it writes a new html file with the included information. I have managed to upload a file successfully and write the html document with the information successfully but i can't get the image to write into the html document. My file_upload.php script contains the variable for the image name, now how would i get the variable string from file_upload.php and use that name in compile.php. Here's my code. -------------- Form.html -------------- <!DOCTYPE html> <html lang="en"> <head> <title></title> </head> <body> <form action="compile.php" method="post"> <p>input name:<input type="text" name="name"/></p><br /> <p>email:<input type="text" name="email" /></p><br /> </form> <br /> <form enctype="multipart/form-data" method="post" action="file_upload.php"> Choose your file here: <input name="file1" type="file" /><br /><br /> <input type="submit" value="Upload It" /> </form> </body> </html> ------------- compile.php ------------- <?php $name = $_POST['name']; $price = $_POST['price']; $desc = $_POST['desc']; $file = "new.html"; $handle = fopen($file,'w'); $data = "<!DOCTYPE html> <html> <head> <title></title> </head> <body> <table style='border-radius:8px;'> <tr> <td style='border-radius:8px;'> <h1>$name</h1> </td> </tr> </table> <table> <tr> <td> <ul> <lh>Product name: $name</lh> <br><br> <li>Price: $price</li><br> <li>Description: $desc</li><br> </ul> </td> <td> <img src='uploads/$fileName' width='' height='' alt='' title='' /> </td> </tr> </table> </body> </html>"; fwrite($handle, $data); print "data written"; fclose($handle); ?> ------------ file_upload.php ------------ <?php // Set local PHP vars from the POST vars sent from our form using the array // of data that the $_FILES global variable contains for this uploaded file $fileName = $_FILES["file1"]["name"]; // The file name $fileTmpLoc = $_FILES["file1"]["tmp_name"]; // File in the PHP tmp folder $fileType = $_FILES["file1"]["type"]; // The type of file it is $fileSize = $_FILES["file1"]["size"]; // File size in bytes $fileErrorMsg = $_FILES["file1"]["error"]; // 0 for false... and 1 for true // Specific Error Handling if you need to run error checking if (!$fileTmpLoc) { // if file not chosen echo "ERROR: Please browse for a file before clicking the upload button."; exit(); } else if($fileSize > 5000000000) { // if file is larger than we want to allow echo "ERROR: Your file was larger than 5mb in file size."; unlink($fileTmpLoc); exit(); } else if (!preg_match("/.(gif|jpg|png)$/i", $fileName) ) { // This condition is only if you wish to allow uploading of specific file types echo "ERROR: Your image was not .gif, .jpg, or .png."; unlink($fileTmpLoc); exit(); } // Place it into your "uploads" folder mow using the move_uploaded_file() function move_uploaded_file($fileTmpLoc, "uploads/$fileName"); // Check to make sure the uploaded file is in place where you want it if (!file_exists("uploads/$fileName")) { echo "ERROR: File not uploaded<br /><br />"; echo "Check folder permissions on the target uploads folder is 0755 or looser.<br /><br />"; echo "Check that your php.ini settings are set to allow over 2 MB files, they are 2MB by default."; exit(); } // Display things to the page so you can see what is happening for testing purposes echo "The file named <strong>$fileName</strong> uploaded successfuly.<br /><br />"; echo "It is <strong>$fileSize</strong> bytes in size.<br /><br />"; echo "It is a <strong>$fileType</strong> type of file.<br /><br />"; echo "The Error Message output for this upload is: <br />$fileErrorMsg"; ?>
