if (!$errors) {
//Call Js function without any events
}
I want to call js function once inside if came,How to call js function inside if condition?Is it possible to call js fucntion without any events inside php tag?
with jquery
if (!$errors) {
echo "<script type='text/javascript'>
$(document).ready(function(){
myfunction();
});
</script>";
}
without jquery and wait unlit whole page is loaded
if (!$errors) {
echo "<script type='text/javascript'>
window.onload = function() {
myfunction();
};
</script>";
}
and without Onload
if (!$errors) {
echo "<script type='text/javascript'>myfunction();</script>";
}
You can also use this way :
<?php
// php code
if(condition){
?>
<script type="text/javascript">
jsFunction();
</script>
<?php
}
// php code
?>
You can also use jquery:
if (!$errors) {
echo "<script type='text/javascript'>
$(document).ready(function(){
myfunction();
});
</script>";
}
You could just make an echo and call it between two script tags.
Like :
if (!$errors) {
echo "<script> myfunction(); </script>";
}

I am trying to call
this js function that is stored on a file called default.js from a php file.
function myfunction(score) {
console.log("got here");
alert(score);
}
so this is the call for the js function on my php code but it does not work.
<!-- myfunction js file ↓ -->
<script type="text/javascript" src="../js/default.js"></script>
<?php
if ($grade=="100%"){
// not able to call
echo "myfunction($grade)";
}
else{
echo "alert(\"haha\")";
}
?>
Try this you will get the accurate result
<?php
if ($grade == "100%") {
?>
<script>
myfunction('<?=$grade?>');
</script>
<?php
} else {
?>
<script>
alert('in');
</script>
<?php } ?>
you forgot about the <script> tags
change your echo like this:
echo "<script>myfunction('$grade')</script>";
you need to wrap ' around the $grade because you're passing a string
or put <script> before the opening php tag and </script> after the end of php tag
This is your Code.
Define $grade too in PHP or you get a
<b>Warning</b>: Undefined variable $grade in <b>
<script type="text/javascript" src="../js/default.js"></script>
<script>
<?php
$grade = "10%";
if ($grade=="100%"){
echo "myfunction('$grade')";
}
else{
echo 'alert("haha");';
}
?>
</script>
Dont forget the <script></script> for javascript code inside html.
I have jQuery function in a PHP function. I have id of a div in a PHP variable. I want to pass this variable to the jQuery code, but it is not working:
public function food(){
echo '<script>
$(document).ready(function () {
$("#$this->ccid #food").show();
});
</script>';
}
Just use string concatenation:
public function food(){
echo '<script>
$(document).ready(function () {
$("#' .$this->ccid. ' #food").show();
});
</script>';
}
I'm trying to execute some PHP code that is using the WooCommerce variable to get the order ID.
add_action('add_meta_boxes', 'gen_order_meta_boxes');
function gen_order_meta_boxes()
{
add_meta_box(
'woocommerce-order-gen',
__( 'TESTNG' ),
'order_meta_box_gen',
'shop_order',
'side',
'default'
);
}
function order_meta_box_gen()
{
echo '<button class="button save_order button-primary alert-mass">Generate</button>';
}
add_action('admin_footer', 'lolcats');
function lolcats()
{
$order = new WC_Order($post_id);
?>
<script type="text/javascript" >
jQuery(document).ready(function($)
{
$(".alert-mass").click(function(e)
{
e.preventDefault();
alert('<?php echo $order->get_order_number; ?>');
});
});
</script>
<?php
}
I can't seem to get it to return anything besides either null or 0.
Using something like this obviously works perfectly: window.location="dhlgen.php?order=1234"; because I'm trying to pass it through the URL to a PHP function which uses it later.
This also seems to fail, but it returns 'false':
function lolcats($post_id)
{
$order = new WC_Order($post_id);
?>
<script type="text/javascript" >
jQuery(document).ready(function($)
{
$(".alert-mass").click(function(e)
{
e.preventDefault();
var data = <?php echo json_encode($order->shipping_first_name); ?>;
alert(data);
});
});
</script>
<?php
}
Thank you.
Okay, I solved it.
function lolcats()
{
global $post;
$order_id = $post->ID;
?>
<script type="text/javascript" >
jQuery(document).ready(function($)
{
$(".alert-mass").click(function(e)
{
e.preventDefault();
alert('<?php echo $order_id; ?>');
});
});
</script>
<?php
}
How could I call function in different jQuery wrapper like this:
<?php
if($trigger != ""){
?>
<script type="text/javascript">
jQuery(document).ready(function($){
var delay = 5000;
setTimeout(rmv, delay); // call the function here
});
</script>
<?php
}
if($triggered != ""){
?>
<script type="text/javascript">
jQuery(document).ready(function($){
function rmv(){ // function to be called
$(".adt_front_wrapper<?php echo $id; ?>").remove();
}
});
</script>
<?php
}
?>
I am trying to call a function which should be separated from the caller like the rmv function in the example code above. How could it be done?
You would need to put that function into a higher (shared) scope. For this example, you could use the window object itself.
window.rmv = function() {
$(".adt_front_wrapper<?php echo $id; ?>").remove();
};
In order to make that work, the declaration and definition of rmv needs to happen beforehand of course.
I want to know if my php variable does not exists, then I want to execute my javascript.
For example-
<?php
if(!isset($_REQUEST['myVar'])){
?>
<script>
alert('variable not exist');
</script>
<?php
}
?>
Is this right way to use javascript code in php extension file
I know all other answers solve your issue but i prefer it to do this way
<script>
<?php
$isset = !isset($_POST['myVar']) ? 'true' : 'false';
echo "var isset = $isset;";
?>
if(isset) {
alert('variable not exist');
}
</script>
when php render your page it will give this output
<script>
var isset = true;
if(isset) {
alert('variable not exist');
}
</script>
Do it like this and it will work:
if (!isset($_REQUEST['myVar'])) {
echo "<script>alert('variable not exist');</script>";
}
you can try writing this piece of code where you want the script to be placed:
<?php
if (!isset($_REQUEST['myVar'])) {
echo '<script>
alert("variable not exist");
</script>';
}
?>
