What am I doing wrong?</p> <p><em><strong></em>**<em>*</em>**<em>*</em></strong> EDIT <strong><em>*</em>**<em>*</em>****</strong></p> <p>Thanks a lot for your comments, but I actually found the solution myself, even if it doesn't make much sense. Instead of using $_POST['box'][0] and [1] at the if statement, I simply used $box[0] and [1]. Even though it's posted, apparently php sees it as a normal array, and not as some kind of $_POST-array! Working code:</p> <pre><code>&lt;form method="post"&gt; &lt;select name="box[]"&gt; &lt;option value="1" &lt;?php if ($box[0] == "1") echo "selected='selected'";?&gt;&gt;1&lt;/option&gt; &lt;option value="2" &lt;?php if ($box[0] == "2") echo "selected='selected'";?&gt;&gt;2&lt;/option&gt; &lt;option value="3" &lt;?php if ($box[0] == "3") echo "selected='selected'";?&gt;&gt;3&lt;/option&gt; &lt;/select&gt; &lt;p&gt; &lt;select name="box[]"&gt; &lt;option value="1" &lt;?php if ($box[1] == "1") echo "selected='selected'";?&gt;&gt;1&lt;/option&gt; &lt;option value="2" &lt;?php if ($box[1] == "2") echo "selected='selected'";?&gt;&gt;2&lt;/option&gt; &lt;option value="3" &lt;?php if ($box[1] == "3") echo "selected='selected'";?&gt;&gt;3&lt;/option&gt; &lt;/select&gt; &lt;p&gt; &lt;input type="submit" value="Submit"&gt; &lt;/form&gt; </code></pre>
