variables displaying many times on same page

**wazo** · Jun 24, 2007, 10:03

Hi guys

Had this problem a couple of times

Some variables are appearing several times

here is 1 example

http://www.notexperienced.co.uk/listings.php?id=22

This has also happened on other parts of the site

Why could this be?

Without seeing code I would have to guess that you have a loop being executed. Find the spot where that variable is being echoed and check its value. If it is wrong find the place before it and see its value there. Keep backtracking until you find where it is being corrupted.

You're using $result for both queries, corrupting it for the first one that way.

What even worse, you're executing the same query in the loop. Don't push your luck, the server might explode! (ok, a bit exaggerating, but that's a bad practice). Load the second query results into an array and then use it in the loop. Although, I'm not sure why do you output the same dates for every job there.

**wazo** · Jun 25, 2007, 10:00

could you point out which bit of code is wrong?

**php_daemon** · Jun 25, 2007, 10:07

Code php:

$result=@mysql_query($query);
 
if(@mysql_num_rows($result) > 0)
{
while($row_articals=@mysql_fetch_array($result))
{
echo $row_articals['MyDate'] . "<br>";
}
}

**wazo** · Jun 25, 2007, 11:35

how should it be?

**php_daemon** · Jun 25, 2007, 13:50

Code php:

$result2=@mysql_query($query);
 
if(@mysql_num_rows($result2) > 0)
{
while($row_articals=@mysql_fetch_array($result2))
{
echo $row_articals['MyDate'] . "<br>";
}
}

Although, that's terrible. I don't see why shouldn't you create that list of dates in advance, then just add that to your jobs list. The dates are the same all the time anyway:

Code php:

$id = $_GET['id'];
 
$query="select *, date_format(startdate,'%D %b %Y') as MyDate from jobs";
$result=@mysql_query($query);
$dates='';
if(@mysql_num_rows($result) > 0)
{
	while($row_articals=@mysql_fetch_array($result))
	{
		$dates.=$row_articals['MyDate'] . "<br>";
	}
}
 
$sql = " select * from jobs where id=$id";
$result = mysql_query ($sql);
 
while ($row = mysql_fetch_array($result))
{
	$field1= $row["jobtitle"];
	$field2= $row["jobdescription"];
	$field3= $row["location"];
	$field4= $row["category"];
	$field5= $row["salary"];
	$field6= $row["firstname"];
	$field7= $row["surname"];
	$field8= $row["email"];
	$field9= $row["telephone"];
	$field10= $row["jobstatus"];
	$field11= $row["company"];        
	$field13= $row["applications"];
	$field14= $row["sublocation"];
	$field15= $row["id"];
 
	echo "<title>$field1</title>";
	echo "<table width=100%><tr><td valign=top><font size=4 ><b>$field1</b></center></td><td align=right>job id:<B>$field15</b></td></tr></table><bR>";
	echo "<table width=100%><tr><td width=58% valign=top>$field2</td><Td align=right valign=top>
