How do you compare array value from this

Code:
<div style="margin: 10px 0pt;" class="result-container">

<p class="list">

<span class="listed">

List Objek:value1

</span>

&lt;input type="hidden" value="1" name="op_value[]" id="op_value"/&gt;

<a class="remove">[remove]</a>

</p>

<p class="list">

<span class="listed">List Objek:value2

</span>

&lt;input type="hidden" value="1" name="op_value[]" id="op_value"/&gt;

<a class="remove">[remove]</a>

</p>

<p class="list">

<span class="listed">List Objek:value3

</span>

&lt;input type="hidden" value="1" name="op_value[]" id="op_value"/&gt;

<a class="remove">[remove]</a>

</p>

I need user to only submit 1 item for every value they choose, if there's a same item in the array then it's validated wrong because the user choose the same item twice.

thanks in advance.

Try writing a custom validation which would use array_unique function.. This will tell you if there is a duplicate entry exists or not.
