i want to pass PHP variable to Javascript array.
It is a test code, but in further i want to pass the printed product id's and name's to this ajax function to send it to cart
The code above is working without printing the button with echo.Any better ideas are welcome :)
<html>
<?php
$num=3;
echo "<button onclick='funkt('<?php echo $num ?>');'>cc</button>
";
?>
</html>
<script>
function funkt(x){
var c=x;
alert(c);
}
</script>
You weren't properly escaping the quotes inside the echo statement. Also, HTML attributes use double quotes (onclick="..."), not single quotes.
Try this:
<!DOCTYPE html>
<html>
<head>
<script>
function funkt(x) {
var c = x;
alert(c);
}
</script>
</head>
<body>
<?php
$num = 3;
echo "<button onclick=\"funkt('" . $num . "');\">cc</button>";
?>
</body>
</html>
Better option is to add an input field of type hidden and pass the number/name/ID to it. On submission of form or button click, you can fetch it wtih the field Id and pass the value to ajax.
<input type="hidden" id="number" value="<?php echo $num;?>" />
<script>
function funkt(x) {
var c = document.querySelector("#number").value;
alert(c);
}
</script>
You can try to declare variable inside "script" tag, and then use this variable in the javascript afterwards like this:
<?php $num = 5; ?>
<script>
var link_label = '<?php echo $num ?>';
//use your link_label value to load it in ajax here or in other files that has been loaded after this script
</script>

I have a JavaScript function for scrolling of table when button is click but I have multiple tables in my code and cant use multiple function for each table I want to store the id's of all table in dynamic way using PHP.
<script type="text/javascript">
// Do something in JavaScript
var x = <?php echo $row_[document_id]; ?>;
// etc..
</script>
document_id is were value are accessed dynamically in PHP.
Instead of using
var x = <?php echo $row_[document_id]; ?>;
you can use something like this:
<?php
echo '<script>var x = ' . $row_document_id . ';</script>';
?>
If data is a string, you can use double quotes:
<?php
echo '<script>var x = "' . $row_document_id . '";</script>';
?>
Also it is preferred to use let instead of var.
Hope that helped.
Save the PHP variable value in HTML hidden input element.
<input type="hidden" value="<?php echo $row_[document_id]?>" id="getValue">
And then get the value from JavaScript or jQuery.
var x = $("#getValue").val();
I am trying to refresh the div content by clicking on href link along with the id(named as data), my actual problem is I'm unable to get the id value with in the script because it is passed with in the function. How to pass the data variable in my php to script? Please check my code below and help me out to solve this. img_div is id of my div which is to be refreshed
PHP:
function printSubDir($dir, $path){
global $data;
$data = $path.''.$dir;
echo "<li><span class=\"toggle\"><a href='asset1.php?data=$data' id='refresh'>$dir</a></span>";
createDir($path.$dir."/");
echo "</li>";
}
Script:
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#refresh').click(function(){
$('#img_div').load('asset1.php #img_div', function() {
});
});
});
</script>
Hi assuming that your variable is $data.You can a php variable in javascript like the following
<?php
$data = "Value of your variable";
?>
<script>
// now a javascript variable data stores the value of your php variable
var data= "<?php echo $data?>";
</script>
I Hope this heps
Echo the id into the function call:
<?php
echo "<a onClick='handleClick($id)'>$dir</a>";
?>
I have this line of code
<script type="text/javascript">
document.title = "<?php include('pot1.php');?>"
</script>
My pot1.php gives me an echo with one random number, but that code does not seem to work and I don't know why the echo doesn't appear in my title. Is anything wrong with the code?
pot1.php code:
<?php
#include_once('link1.php');
$cg = fetchinfo("value","info","name","current_game");
$cb = fetchinfo("cost","games","id",$cg);
$cb=round($cb,2);
echo '$'.$cb;
?>
This echo is working and is giving me values because I can see them in one div.
You should just do it like this:
<?php include('pot1.php');?>
Now we know that there is a variable set. Echo that into the title tag.
<script type="text/javascript">
document.title = "<? echo $cb ?>"
</script>
The way you're doing it now... I don't think you can include an entire PHP page and expect to behave like a simple string, even if that's all it returns.
Put the value you want inside a variable in the pot1.php file and use it on the title
<?php include('pot1.php');?>
<script type="text/javascript">
document.title = "<?php echo $yourVar;?>"
</script>
I am using the below code to call the javascript function from php script. Its not working while am adding the php variable in javascript($msg). Please help me to do this.
if ( isset($_GET['Error'])) {
$msg =$_GET["Error"];
echo '<script type="script.php">validate("Error",$msg);</script>';
}
You have to quote the $msg or it will be syntax error in javascript.
And the type is non sense.
Since the msg is from the $_GET, don't forget the escape it.
if ( isset($_GET['Error'])) {
$msg =$_GET["Error"];
echo '<script>validate("Error", "'.htmlspecialchars($msg).'");</script>';
}
Instead of an inline script, this should work:
<html>
<head>
<script type="text/javascript">
function testMe(x){
alert(x);
}
</script>
</head>
<body>
<?php
$phpVar = 'I am a PHP variable';
echo "Click Me";
?>
</body>
<html>
Is there a way I can pass the php option value variable $option_value['price'] into javascript as a string, then each time a different option is chosen, the javascript 'updates' the string with the new value. I have tried with onchange() but must be doing something wrong. I am sure my mistake is because php is server side and javascript is client side, but I have no idea how to get the two to act how I want.
<?php if ($options) { ?>
<?php foreach ($options as $option) { ?>
<?php if ($option['type'] == 'select') { ?>
<span id="option-<?php echo $option['product_option_id']; ?>" class="option">
<select name="option[<?php echo $option['product_option_id']; ?>]" onchange="getIt(this)">
<?php foreach ($option['option_value'] as $option_value) { ?>
<option value="<?php echo $option_value['product_option_value_id']; ?>"><?php echo $option_value['name']; ?>
<?php if ($option_value['price']) { ?>
<?php $option_value['price']; ?>
<?php } ?>
</option>
<?php } ?>
</select>
</span>
I have tried:
<script type="text/javascript">
function getIt(elm) {
var val = elm.options[elm.selectedIndex].text;
window.alert(val);
}
</script>
and
<script type="text/javascript">
function getIt() {
var val = "<?php $option_value['price']; ?>";
window.alert(val);
}
</script>
Here is an example how you can do it. What you have to do are:
Analyze the code (notice that I use jquery from google's account. You will need to at some point install jquery on your web site and use this one instead of the google's one.
Build your fruits array so it looks like the one in the example.
I have prepared page that will show you this working here: http://jsfiddle.net/7uudp/
Below is what it contains. Notice that this example does not use your variables. You will need to use them the way you want/need. I have also defined entry_fruit to show you how to chose the default one to be selected. Hope it will help.
<html>
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script type="text/javascript">
fruits = [{n:"apple",p:1},{"n":"strawbery",p:3}];
entry_fruit="strawbery";
function build_select(select,list,which)
{
$.each( list, function(i,v){
var selopt="" ;
if ( v.n == which ) selopt="selected" ;
$(select).append("<option "+selopt+" value="+i+">"+v.n+" - $"+v.p+"</option>");
}) ;
}
$(document).ready(function(){
build_select($("select[name=fruits]"),fruits,entry_fruit);
$("select[name=fruits]").change(function(){
alert("Price is $" + fruits[$(this).val()].p);
}) ;
})
</script>
</head>
<body>
<select name="fruits"></select>
</body>
</html>
<script type="text/javascript">
function getIt() {
var val = "<?php echo $option_value['price']; ?>";
window.alert(val);
}
</script>
Like so? Looks to me like you just forgot the "echo".
EDIT-
<script type="text/javascript">
var val = "<?php echo $option_value['price']; ?>";
function getIt(elm) {
val = elm.options[elm.selectedIndex].text;
window.alert(val);
}
</script>
Okay, Revoking my previous entry.
What you need to do is to add selected keyword to your <option> element when you match your option_value['price']
Now yuou need to arrange your data in a little bit different way.
In your javascript, prepare an array that will map $option_value['product_option_value_id'] to $option_value['price'];. When you build your <select>, for each $option_value['product_option_value_id'] check if its price matches the one that came in initially from php.
Your getIt will simply take the <option value="___"> value, find it in that map, and show it to the user using the alert() window.
