Html Multiple Input Elements With Same Name

I came across a specific and interesting problem yesterday. Assume we have the following html code block:

<div id="addresses">
 <input type="text" name="address" id="addr1" />
 <input type="text" name="address" id="addr2" />
 <input type="text" name="address" id="addr3" />
</div>

While posting this form, input elements that have the same name are joined and values are separated with comma character. For example if we have the values like:

addr1 = 'TEST TEST XXX'
addr2 = 'YYY ZZZ 11111'
addr3 = 'ZZZ KKK TEST '

submitted form post data is as follows: 

address = 'TEST TEST XXX', 'YYY ZZZ 11111', 'ZZZ KKK TEST '

then i can get each of these values as elements of an array on the server side (3 different elements of array). But if the values are like:

addr1 = 'TEST, TEST XXX'
addr2 = 'YYY ZZZ, 11111'
addr3 = 'ZZZ KKK, TEST '

then submitted form data becomes:

address = 'TEST, TEST XXX', 'YYY ZZZ, 11111', 'ZZZ KKK, TEST '

then the resulting array contains 6 elements which is totally wrong. I believe COMMA character which is contained in the value is not escaped.

Any ideas on this issue. Thanks in advance...

Use this HTML

<div id="addresses">
    <form:input path="address[0]"  />
    <form:input path="address[1]"  />
    <form:input path="address[2]"  />
</div>

and Spring should populate your input texts with the values of the String[] address server-side object and vice-versa.

You are not using an array.

Change each input like this:

<input type="text" name="address[]" id="addr1" />

and when you will fetch the data you will have an array without any issue about comma or else.

$_POST['adddess']=array(0=>'TEST, TEST XXX',1=>'YYY ZZZ, 11111',2=>'ZZZ KKK, TEST ');

and you can access each item based on the index

Instead of using multiple input fields with one NAME attribute value, use unique values. That can make your code much more robust.

<div id="addresses">
 <input type="text" name="addr1" id="addr1" />
 <input type="text" name="addr2" id="addr2" />
 <input type="text" name="addr3" id="addr3" />
</div>

On the php side:

<?php
$address = array($_REQUEST['addr1'], $_REQUEST['addr2'], $_REQUEST['addr3']);
?>
