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-
[html]
<!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>
[/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]
<?php
$address = $_POST[‘address’];
foreach($address as $value)
echo $value . "<br />";
?>
[/php]
[wpdm_file id=105]
Output:
1589 Tyler Avenue
Miami, FL 33169
USA
