The first statement is populated by a query of a table on the server. The Second has 3 values: Elite, Core, Raider. Using AJAX and PHP I'm trying to make it so when someone selects a name from the first the second one always changes to the value that is in the database for that person; however this must remain a select in case an unoted switch happens(in which case the value of the second must be changed).</p> <pre><code>&lt;?php echo "&lt;select name='playername' onchange='filldata(this.value)'&gt;"; require("/home/a9299818/public_html/DKPTools/connect.php"); $query1 = mysql_query("SELECT player.id, player.primarytoon, player.rank, IFNULL( SUM(dkp.dkp ) , 0 ) FROM player LEFT OUTER JOIN dkp ON player.id = dkp.player_id GROUP BY player.id ORDER BY player.id"); while ($row = mysql_fetch_array($query1, MYSQL_NUM)){printf("&lt;option value='%s'&gt;%s&lt;/option&gt;",$row[0],$row[1]);} echo "&lt;/select&gt;"; echo "&lt;select name='rank'&gt;&lt;option value='1'&gt;Elite&lt;/option&gt;&lt;option value='2'&gt;Core&lt;/option&gt;&lt;option value='3'&gt;Raider&lt;/option&gt;"; ?&gt; </code></pre> <p>This PHP works and populates both selects correctly; however I'm totally lost in coding the AJAX which should change rank.value to whatever the database says it is WITHOUT REFRESHING THE PAGE.</p>

    1. CONot in this case, the values of the second drop down are static and the options do not change. Only the Value should when the first is changed, but the value is still one of the first 3 options.

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.
