    <p>I can't set a variable from a post array. </p> <p>I have a simple form with a hidden field in it: <code>&lt;input name="sid" type="hidden" id="sid" value="&lt;?=$sid?&gt;"&gt;</code></p> <p>This hidden field gets sent off to a second file (exec.php) where I have the following code:</p> <pre><code>$sid = $_POST['sid']; </code></pre> <p>For some reason, when trying to set $sid, it gets a NULL value. For haha's, I ran the following:</p> <pre><code>foreach($_POST as $var =&gt; $value) { echo $var . ' : ' . $value . "&lt;br&gt;"; } </code></pre> <p>This provided a correct value of 1938 for sid. I've looked at this for 3 hours and can't find what is happening. I expect something extremely stupid...any thoughts? </p> <hr> <p>Here is the form on enter.php</p> <pre><code> &lt;form name="form1" method="post" action="exec.php"&gt; &lt;input name="sid" type="hidden" id="sid" value="&lt;? echo($sid); ?&gt;"&gt; &lt;input name="ticket_totals" type="hidden" id="ticket_totals" value="&lt;?=$ticket_totals?&gt;"&gt; &lt;input name="emp" type="hidden" id="emp" value="&lt;?=$emp?&gt;"&gt; &lt;input name="submit" type="submit" id="submit" value="Submit"&gt; &lt;input type="submit" name="submit" id="submit" value="Close"&gt; &lt;/form&gt; </code></pre> <p>Here is the POST output on exec.php: type : Other ticket_totals : 0 emp : 105 sid : 1939 submit : Submit</p> <hr> <p>Okay - this was poor syntax on my part but now I'm curious as to why.</p> <p>I left out quotation marks - the solution is as simple as this: $sid = $_POST["sid"]</p> <p>Now it works like a champ.</p> <p>Any takers on why? I'd guess there is a setting in the php.ini that requires the quotes. Strangely enough, I have other variables called from the POST array that i'm not using quotes for and they're working fine...</p>

    1. COPlace an `var_dump($sid);` directly below `$sid = $_POST['sid'];`. Your error certainly lies elsewhere.

    2. COare you able to cut and paste the output from foreach($_POST as $var => $value), so we can verify there isn't a typo or something as that seems rather strange.

    3. COare you sure that output is correct, the following form fields are missing from it. shift_id, emp and your POST output shows another field "type" which is not on your form

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
