Re: make link from a variable.

this is a typo error in your SQL query then

Click to Expand / Collapse Quote originally posted by navi17 ...

..........
it should be:
PHP Syntax (Toggle Plain Text)
$myquery = "select * from lesson where subject like '%'.$q.'%' AND learningArea like '%'.$r.'%' AND ability like '%'.$s.'%'";
$myquery = "select * from lesson where subject like '%'.$q.'%' AND learningArea like '%'.$r.'%' AND ability like '%'.$s.'%'";
........

and,
the SQL save version is this:

php Syntax (Toggle Plain Text)
$q = isset($_GET['q'])? mysql_real_escape_string($_GET['q']):'';
$r = isset($_GET['r'])? mysql_real_escape_string($_GET['r']):'';
$s = isset($_GET['s'])? mysql_real_escape_string($_GET['s']):'';
 
// Build SQL Query
$myquery = "select * from lesson where subject like '%{$q}%' AND learningArea like '%{$r}%'
 AND ability like '%{$s}%'";
$q = isset($_GET['q'])? mysql_real_escape_string($_GET['q']):'';
$r = isset($_GET['r'])? mysql_real_escape_string($_GET['r']):'';
$s = isset($_GET['s'])? mysql_real_escape_string($_GET['s']):'';

// Build SQL Query
$myquery = "select * from lesson where subject like '%{$q}%' AND learningArea like '%{$r}%'
 AND ability like '%{$s}%'";

Re: make link from a variable.

try this:

PHP Syntax (Toggle Plain Text)
while ($row= mysql_fetch_array($result))
{
$lessonID = $row["lessonID"];
$subject = $row["subject"];
$learningArea= $row["learningArea"];
$noofstudent= $row["noofstudents"];
$minutes= $row["minutes"];
$class= $row["class"];
$ability= $row["ability"];
 
?>
//display the row
 
<tr>
<td><a href="details.php?lessonID=<?php echo $lessonID; ?>"> Details</a></td>
<td><?php echo $subject; ?></td>
<td><?php echo $learningArea; ?></td>
<td><?php echo $noofstudents; ?></td>
<td><?php echo $minutes; ?></td>
<td><?php echo $class; ?></td>
<td><?php echo $ability; ?> </td>
</tr>
<?php  } ?>
</table>
while ($row= mysql_fetch_array($result))
{
$lessonID = $row["lessonID"];
$subject = $row["subject"];
$learningArea= $row["learningArea"];
$noofstudent= $row["noofstudents"];
$minutes= $row["minutes"];
$class= $row["class"];
$ability= $row["ability"];

?>
//display the row

<tr>
<td><a href="details.php?lessonID=<?php echo $lessonID; ?>"> Details</a></td>
<td><?php echo $subject; ?></td>
<td><?php echo $learningArea; ?></td>
<td><?php echo $noofstudents; ?></td>
<td><?php echo $minutes; ?></td>
<td><?php echo $class; ?></td>
<td><?php echo $ability; ?> </td>
</tr>
<?php  } ?>
</table>

i am sure it works.

i've seen your first version, and in that post i did not see the <?php echo $field... ; ?>
which needed to print the values.

if i saw it wrong then sorry about it.

Hi Navi17.
thanks a lot..can be linked to details page.
however, the Id number is not shown in the result..
all show the same string..details..but the lesson Id that sent to details page is correct (the lessonID)
just the Id is not displayed in the table.
any idea to correct it?

thanks

djjjozsi, it does work for me..I mean the link.
the code that I posted before also print data from the database..
The problem is to make a link to the details page.
now, Navi17 has solved that problem..however the ID is not printed here..but the value is passed to the details page... I need both..the lessonID printed & the value passed.
ANy solution. Mny thanks for your respond
