    <p>I'll explain a little bit more.</p> <p>I have a JQuery datatable, and through CSS I have different <code>&lt;tr classes&gt;</code>. Depending on the information stored in the database, these <code>&lt;tr&gt;</code> get a different class, thus a different color in the datatable.</p> <p>Now for one <code>&lt;tr class&gt;</code> I'd like to give the user the option to hide/show. I was thinking to do this with a checkbox, and the javascript would parse an url when checked, and remove it when unchecked again. This URL can be used for php to run different queries, if <code>$_GET['parsedurl']</code>: query to show all tables, elseif <code>$_GET['empty']</code>: query for not showing that 1 information.</p> <p>But this is the worst way to do it. I need to find something to toggle the <code>display: none</code> on or off of the table class, since this is working client-side.</p> <p>So Im now thinking to keep the parsing of the javascript in an URL and depending on the URL, I run the .php GET to echo out <code>&lt;tr style: display: none&gt;</code> or just simply <code>&lt;tr&gt;</code></p> <p>Therefore I need some javascript which does this:</p> <ul> <li>If checkbox is checked, redirect to projectlist.php?showpastdate</li> <li>When URL = projectlist.php?showpastdate, make checkbox checked.</li> <li>When URL = projectlist.php?showpastdate and checkbox gets unchecked, redirect to projectlist.php, where the checkbox is unchecked.<br /></li> </ul> <p>I think these triggers are the best options?</p> <p>With .PHP I'll do:<br /></p> <pre><code>if (isset($_GET['showpastdate'])) { &lt;tr style: display: none&gt; } else { &lt;tr&gt; } </code></pre> <p>Maybe someone has an even better solution? I'd like to hear!</p> <p>Thanks.</p> <p><strong>EDIT</strong></p> <p>The javascript I now have is:</p> <pre><code>&lt;script&gt; function toggleAutoRefresh(cb) { if (cb.checked) { window.location.replace("?showpastdate"); } // If a checkbox named "cb" is checked, and the url contains "?showpastedate" if ((cb.checked) &amp;&amp; !~window.location.href.indexOf("?showpastdate")) { //Uncheck the checkbox and remove the "?showpastedate" from the url document.getElementById("showpastdate").checked = false; window.location.href.replace("?showpastdate",""); } else { // Else, check the checkbox and add the "?showpastedate" to the url document.getElementById("showpastdate").checked = true; window.location.href += "?showpastdate"; } } &lt;/script&gt; </code></pre> <p>After checking the checkbox, it goes to the page projectlist.php?showpastdate and gets unchecked there. When checking again, it goes to projectlist.php?showpastdate?showpastdate. It should remove the ?showpastdate, not add another.</p> <p>This is could do with PHP too, but I really don´t like a submit button for this checkbox. Just check and execute.</p>

    1. COYou forgot the `,""` in your first `if`, in the last code block. It should be: `window.location.href.replace("?showpastdate","");`

    2. COActually, if the page loads with the checkbox checked ("?showpastdate" being in the url), it shouldn't do anything, right? (Aside from keeping the checkbox checked) In that case, remove the entire `if` block.

    3. COIf I place "" beside (1st if block), doesn't change anything. If I remove the (1st) if block, can't even check the checkbox, guess cos it refreshes

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.
