Hide if db field is empty

[vikingbear_ds]

Hi, using php and mySQL

I am trying to hide items in a list if the field is empty in the database, this function has worked in teh past, but in this case the <li> is still displaying on the page..

 <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
  <li><a><?php echo $row_rsOsprey['tour_header_08']; ?></a></li>
  <?php } // Show if recordset not empty ?>

ANy suggestions?

Regards, Ken

What is $totalRows_rsOsprey set to?

Hi Guru,

I should probably mention that the <li> is part of a JQUERY tab system,
I tried to 'hide' one of the <div> statements as well..
What do you mean by 'What is $totalRows_rsOsprey set to?' are you thinking field type in database?

 

 

<ul>
<?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
  	<li><a><?php echo $row_rsOsprey['tour_header_02']; ?></a></li>
  <?php } // Show if recordset not empty ?>
  <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
    <li><a><?php echo $row_rsOsprey['tour_header_03']; ?></a></li>
    <?php } // Show if recordset not empty ?>
  <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
    <li><a><?php echo $row_rsOsprey['tour_header_04']; ?></a></li>
    <?php } // Show if recordset not empty ?>
  <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
    <li><a><?php echo $row_rsOsprey['tour_header_05']; ?></a></li>
    <?php } // Show if recordset not empty ?>
  <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
    <li><a><?php echo $row_rsOsprey['tour_header_06']; ?></a></li>
    <?php } // Show if recordset not empty ?>
  <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
    <li><a><?php echo $row_rsOsprey['tour_header_07']; ?></a></li>
    <?php } // Show if recordset not empty ?>
  <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
  <li><a><?php echo $row_rsOsprey['tour_header_08']; ?></a></li>
  <?php } // Show if recordset not empty ?>
</ul>
			<div>
				<div><?php echo $row_rsOsprey['tour_text_02']; ?></div>
        		<div><?php echo $row_rsOsprey['tour_text_03']; ?></div>
				<div><?php echo $row_rsOsprey['tour_text_04']; ?></div>
        		<div><?php echo $row_rsOsprey['tour_text_05']; ?></div>
				<div><?php echo $row_rsOsprey['tour_text_06']; ?></div>
        		<div><?php echo $row_rsOsprey['tour_text_07']; ?></div>
                <?php if ($totalRows_rsOsprey > 0) { // Show if recordset not empty ?>
  <div><?php echo $row_rsOsprey['tour_text_08']; ?></div>
  <?php } // Show if recordset not empty ?>
            </div>

*smh* what is the value? What makes you think the code isn't working?

Hi Gury..

You can see the last TAB is still showing althought there is no data fed from database..

[Jessica]

Registered member, echo the variable and see what's actually in it.

var_dump

Hi Gury,
I should also have explained that I am a coding novice..
I tried <?php echo $row_rsOsprey['tour_header_08']; var_dump($tour_header_08); ?>

and got an error in the browser ;

PHP Notice:  Undefined variable: tour_header_08 in C:\inetpub\wwwroot\2013.downunderdive.com.au\osprey_v_cruise.php on line 609

<?php

var_dump($row_rsOsprey);

echo $row_rsOsprey['tour_header_08'];

?>

 

Try this ^ instead.

Hey Nerbie, Your if condition is:

 

$totalRows_rsOsprey > 0

 

You say the li still prints? Then $totalRows_rsOsprey must be greater than 0.

 

Your code literally makes no sense though. You could put all of that within the same loop. But really you should probably look into normalizing your data and using loops.

Solved it, (and looking back it makes sense) Thanks for everybody's time and input!

 

<?php if ($totalRows_rsOsprey['tour_header_08'] > 0) { // Show if recordset not empty ?>
  <li><a><?php echo $row_rsOsprey['tour_header_08']; ?></a></li>
  <?php } // Show if recordset not empty ?>
