Body
<p>I run the code you did and it works for me. The only change I made was creating the form element. I have to create a table to make it functional. I did not go throughout village. I stopped when I got districts working.</p> <p>Here is the code I changed:</p> <pre><code><?php $db = mysql_connect('127.0.0.1','root') or die('could not connect'); mysql_select_db('financial_system_local',$db); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Register Page</title> <link href="style/stylesheet.css" rel="stylesheet" type="text/css" /> <link href="style/imagesGallery.css"rel="stylesheet" type="text/css"/> <SCRIPT language=JavaScript> function reload(form) { var val=form.governorate.options[form.governorate.options.selectedIndex].value; self.location='register.php?governorate=' + val ; } function reload3(form) { var val=form.governorate.options[form.governorate.options.selectedIndex].value; var val2=form.district.options[form.district.options.selectedIndex].value; self.location='register.php?governorate=' + val + '&district=' + val2 ; } </script> </head> <body> <form> <?php $governorate = ""; $district = ""; //$quer2=mysql_query("SELECT DISTINCT category,cat_id FROM category order by category"); $quer2=mysql_query("SELECT DISTINCT governorate_name,governorate_id FROM governorate order by governorate_name",$db); echo mysql_error($db); //$cat=$_GET['cat']; $governorate=$_GET['governorate']; var_dump($governorate); if(isset($governorate) and strlen($governorate) > 0) { $quer=mysql_query("SELECT DISTINCT district_name,district_id FROM districts where governorate_id=$governorate order by district_name",$db); } else { $quer=mysql_query("SELECT DISTINCT district_name,district_id FROM districts order by district_name",$db); } $district=$_GET['district']; if(isset($district) and strlen($district) > 0){ $quer3=mysql_query("SELECT DISTINCT village_name FROM village where district_id=$district order by village_name"); } else { $quer3=mysql_query("SELECT DISTINCT village_name FROM village order by village_name"); } echo "<select name='governorate' onchange=\"reload(this.form)\"><option value=''>Select one</option>"; while($noticia2 = mysql_fetch_array($quer2)) { if($noticia2['governorate_id']==@$governorate) { echo "<option selected value='$noticia2[governorate_id]'>$noticia2[governorate_name]</option>"."<BR>"; } else { echo "<option value='$noticia2[governorate_id]'>$noticia2[governorate_name]</option>"; } } echo "</select>"; echo "<select name='district' onchange=\"reload3(this.form)\"><option value=''>Select one</option>"; while($noticia = mysql_fetch_array($quer)) { if($noticia['district_id']==@$district) { echo "<option selected value='$noticia[district_id]'>$noticia[district_name]</option>"."<BR>"; } else { echo "<option value='$noticia[district_id]'>$noticia[district_name]</option>"; } } echo "</select>"; echo "<select name='village' ><option value=''>Select one</option>"; while($noticia = mysql_fetch_array($quer3)) { echo "<option value='$noticia[village_name]'>$noticia[village_name]</option>"; } echo "</select>"; ?> </form> </code></pre>

Guidance

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.
