    <p>Right then, I seem to have misunderstood something about cookies. Why doesn't this work...</p> <pre><code>&lt;?php if (isset($_COOKIE["stop"])){ echo "Welcome " . $_COOKIE["stop"] . "!&lt;br /&gt;"; } $passedvar = $_POST["stopsaway"]; if (isset($passedvar)){ echo "HHHYES!!!"; if (is_numeric($passedvar)){ echo "Yup its a number string alright! I'll turn it into a int and I'll make a cookie."; //$passedvar = (int)$passedvar; setcookie("stop", $passedvar, time()+30); echo "COOKIE MADE."; } } if (isset($_COOKIE["stop"])){ echo "Welcome " . $_COOKIE["stop"] . "!&lt;br /&gt;"; } //var_dump($_POST["stopsaway"]); ?&gt; </code></pre> <p>SECOND CODE</p> <pre><code>&lt;?php $thing = 1; if ($thing==1){ setcookie("stop","4",time()+30); } if (isset($_COOKIE["stop"])){ echo "So why won't it work THERE!?"; } print_r($_COOKIE); ?&gt; </code></pre> <p>Basically, I want the user to enter a number into a field, and then a cookie is set to that number, and the main page reflects that change. This worked ONCE. The bottom code seems to work, but for some reason it doesn't work unless I manually type in the url to go to the main page using the cookie page window. If I have the two tabs open next to eachother...it doesn't do anything just to refresh the main page after creating the cookie....I wonder why.</p> <p>Also, I remember hearing that nothing can come before setcookie, for it to work it has to be the very first line of code..... So then how am I supposed to check the input first, or other conditionals? Thanks! Oh right, and I'm using Firefox, but I've tested on my Android as well. And it's working on one page but not another so I don't think it's the browser.</p>

    1. COI think the problem is that `+30` it is a tiny time if I remember correctly that 30 means 30 millisecond...make it like 3000 for 3 seconds

    3. COSo I could keep the conditionals as long as they don't use echo or something? I deleted the echos, seems to do the trick. Thanks!! And Sean no it's using seconds.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
