I have a form with multiple textboxes with the same names. I want to get the data from all the textboxes in my PHP code.
Here is my code.
Email 1:<input name="email" type="text"/><br/>
Email 2:<input name="email" type="text"/><br/>
Email 3:<input name="email" type="text"/><br/>
$email = $_POST['email'];
echo $email;
I wanted to have a result like this:
Instead I only get the text from the last textbox.
Using [] in the element name
Email 1:<input name="email[]" type="text"><br>
Email 2:<input name="email[]" type="text"><br>
Email 3:<input name="email[]" type="text"><br>
will return an array on the PHP end:
$email = $_POST['email'];
you can implode() that to get the result you want:
echo implode(", ", $email); // Will output [email protected], [email protected] ...
Don't forget to sanitize these values before doing anything with them, e.g. serializing the array or inserting them into a database! Just because they're in an array doesn't mean they are safe.
<input name="email[]" type="text">
<input name="email[]" type="text">
<input name="email[]" type="text">
<input name="email[]" type="text">
$_POST['email'] will be an array.
Another example could be:
<input type="text" name="email[]" value="1">
<input type="text" name="email[]" value="2">
<input type="text" name="email[]" value="3">
<?php
foreach($_REQUEST['email'] as $key => $value)
echo "key $key is $value <br>";
will display
key 0 is 1
key 1 is 2
key 2 is 3
