Hiii everyone,
I just want to show one div if the database value is equal to some value.I tried like this
<?php echo $show['birth_certificate_available']=='Available') { ?>
<script type="text/javascript">
$(".birth").show();
</script>
<?php } ?>
But the div is not showing.I dont know why its not working.Kindly guide me to correct this issue.
Please modify the code accordingly :
<?php if($show['birth_certificate_available']=='Available') { // put a condition?>
<script type="text/javascript">
$(document).ready(function(){ // jQuery ready function
$(".birth").show();
});
</script>
<?php } ?>
// put a condition?> because it can confuse wheter or not the ?> tag is executed
Wrap it in ready() function as follows,
Assuming you have already imported the relevant jquery lib in your code.
<?php echo $show['birth_certificate_available']=='Available') { ?>
<script type="text/javascript">
$(document).ready(function(){
$(".birth").show();
});
</script>
<?php } ?>
I missed JQuery reference document so that its not worked.Now I added script document its working.Thanks all who helped me to fix this.
echo outputs data to the page. To write a condition, you would like to use if statements.
<?php if ($show['birth_certificate_available'] === 'Available'): ?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('.birth').show();
});
</script>
<?php endif; ?>
Note: if jQuery is already linked to your document, remove the <script src="..."></script> line. Otherwise, I suggest you to move the <script src="..."></script> line right before the </body> HTML closing tag to speedup HTML elements loading:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<div class="birth" hidden="hidden">Foobar</div>
<?php if ($show['birth_certificate_available'] === 'Available'): ?>
<script>
$(document).ready(function() {
$('.birth').show();
});
</script>
<?php endif; ?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</body>
</html>
Note: I use the === equal assertion to force type testing. Whatever, be careful: testing is case-sensitive, whether it is == or ===
The
divelement must have thebirthclass, must exist and must be hidden in order to successfullyshow()it
$show variableIf this is not working, and in order to debug the $show variable, you may want to use var_dump() as so:
var_dump($show);
and ensure it is an array and has the birth_certificate_available index defined.
Use the browser console to retrieve javascript errors (such as inexisting div elements...)
<div /> element with the class birth as something like this: <div class="birth">? Does the <div /> element hidden? Does it exist at the page creation?div element existing? Has it the hidden="hidden" attribute and value? (or equivalent)
$show. You need to know first if it goes through your condition, so just usevar_dump($show)and write down below your code snippet what it displayed on your screen.
