Is there an equivalent in php to the MySQL "IN" phrase?

[kuau]

I'm trying to do this:


DISPLAY all the categories and echo " checked" WHERE cat_id IN (SELECT cat_id FROM eventcategories WHERE event_id = $event_id);

I can't believe this could be such a difficult thing to do. I just can't get past it. Please help.

Also, my page hangs there grinding away with the message "one item remaining." How do I find out what is causing that? and what is the one item?

Plz post the PHP source code so that the correct SQL statements you uses can be viewed.

Well, here is the code that correctly lists the categories and the checkboxes:


$sql = "SELECT cat_id, category FROM category ORDER BY category";
$result_cat = mysql_query($sql,$connection) or die("Couldn't execute $sql query. <br> mysql error: ".mysql_error());
$count=0;
while ($row = mysql_fetch_array($result_cat))
{
$count++;
echo '<td width="253"><input type="checkbox" name="cats[]" value="'.$row['cat_id'].'">' .$row['category'].'</td>';
if (($count % 3) == 0){
echo "</tr>";
}
}

To get the categories for a particular event_id I tried this but it didn't work:


$sql = "SELECT * FROM eventcat WHERE event_id = '".$_GET['event_id']."' ";
$result_evcat = mysql_query($sql,$connection) or die("Couldn't execute $sql query. <br> mysql error: ".mysql_error());
while($row = mysql_fetch_array($result_evcat))
{ $count++;
$evcat_id = $row['cat_id'];
}

with this in the output line:


<td width="253"><input type="checkbox" name="cats[]" value="<?php echo $row['cat_id'];?>"<?php if($row['cat_id'] == $evcat_id){echo " checked";}?>> <?php echo $row['category'];?></td>';
