  1. POCheckbox "checked"-value jumps up to earlier array values, when array is empty
    text
    copied!<p>I have an array of checkboxes name="box[]". Through PHP I make sure that they're checked after they're submitted by echoing "checked='checked'" if they were checked at submit event.</p> <p>Now, if I check the third box, the value jumps down to the first checkbox after submit, since the array was empty up until the third checkbox. Same, if I check the 2nd and 3rd checkbox, they jump down to 1st and 2nd after submit. This is the code I'm using:</p> <pre><code>&lt;form method="post"&gt; &lt;input type="checkbox" name="box[]" value="true" &lt;?php if ($box[0] == true) echo "checked='checked'"; ?&gt;&gt;&lt;br&gt; &lt;input type="checkbox" name="box[]" value="true" &lt;?php if ($box[1] == true) echo "checked='checked'"; ?&gt;&gt;&lt;br&gt; &lt;input type="checkbox" name="box[]" value="true" &lt;?php if ($box[2] == true) echo "checked='checked'"; ?&gt;&gt;&lt;br&gt; &lt;p&gt; &lt;input type="submit" value="Submit"&gt; &lt;/form&gt; </code></pre> <p>Try it at: <a href="http://experiencerapanui.com/selecttest.php" rel="nofollow">http://experiencerapanui.com/selecttest.php</a></p> <p>Can I make the checkboxes fill up the array with a value "false" or whatever, if the box is unchecked? Which way should I go?</p> <p><em><strong></em>**<em>*</em>***<em></strong> EDIT <strong></em>**<em>*</em>**<em>*</em></strong></p> <p>Thanks to phant0m, I managed to come up with a solution:</p> <pre><code>&lt;form method="post"&gt; &lt;input type="checkbox" name="box[]" value="1" &lt;?php if (in_array("1", $box)) echo "checked='checked'"; ?&gt;&gt;&lt;br&gt; &lt;input type="checkbox" name="box[]" value="2" &lt;?php if (in_array("2", $box)) echo "checked='checked'"; ?&gt;&gt;&lt;br&gt; &lt;input type="checkbox" name="box[]" value="3" &lt;?php if (in_array("3", $box)) echo "checked='checked'"; ?&gt;&gt;&lt;br&gt; &lt;p&gt; &lt;input type="submit" value="Submit"&gt; &lt;/form&gt; </code></pre> <p>Putting unique values for the checkboxes, then if I find the value in the array $box[], the box is marked as checked.</p>
