Problem:
In your HTML form there may have multiple form fields for a single title. For ex. address (see the following picture), it has multiple input boxes. You declared the same name as address[] for all the boxes. Now, when someone enters the address fields and submit the form, you want to retrieve the full address in the PHP page.
Solution:
Let’s see the process step by step-
Step 1: The form code
Let’s start from the HTML form. Here is the code for the above HTML form-
<!doctype html> <html> <head> <meta charset="utf-8"> <title>How to Pass Form Input Array to a PHP Page</title> <style> div.left{ float:left; display:block; width:10%; text-align:right; padding-right:5px; height:75px; } input.txtbox{ width:240px; } div.right{ float:left; display:block; width:85%; height:25px; } input.btn{ margin-left:10.25%; } </style> </head> <body> <form action="submit.php" method="post"> <div class="left">Address :</div> <div class="right"><input name="address[]" type="text" class="txtbox"></div> <div class="right"><input name="address[]" type="text" class="txtbox"></div> <div class="right"><input name="address[]" type="text" class="txtbox"></div> <input name="Submit" type="submit" value="Submit" class="btn"> </form> </body> </html>
Please note that we’ve declared all the address fields with the same array name – address[].
Step 2: The PHP code
Now, let’s see how we read the address[] array variables in the PHP code next page after someone submit the form entering his address-
<?php $address = $_POST['address']; foreach($address as $value) echo $value . "<br />"; ?>
[wpdm_file id=105]
Output:
1589 Tyler Avenue
Miami, FL 33169
USA
