PHP: javascript alert, with value from sql query, into IF condition

With the following code, a popup table should appear with sql query data, only when retrieved records are greater than 1.
$sql = "SELECT * FROM pt_locations WHERE country = ('$countryCode') AND location = ('$cityCode')";
$result = $conn->query($sql);
$rowcount=mysqli_num_rows($result);
$message = "Records found: " . $rowcount . "<br /><br />";
if ($rowcount > 1) {
echo '<script language="javascript">';
echo 'alert' .$message;
foreach($result as $val){
$id_country = $val["country"] ;
$id_code = $val["code"] ;
$id_location = $val["location"] ;
$id_latitude = $val["latitude"] ;
$id_longitude = $val["longitude"] ;
echo "<table border='1' cellpadding='5'>";
echo "<tr>";
echo "<td><i><strong>ID Code</strong></i></td><td>";
echo $id_code."</td>";
echo "<td><i><strong>Country</strong></i></td><td>";
echo $id_country."</td>";
echo "<td><i><strong>Code</strong></i></td><td>";
echo $code."</td>";
echo "<td><i><strong>Location</strong></i></td><td>";
echo $id_location."</td>";
echo "<td><i><strong>Latitude</strong></i></td><td>";
echo $id_latitude."</td>";
echo "<td><i><strong>Longitude</strong></i></td><td>";
echo $id_longitude."</td>";
echo "</tr>";
echo "</table><br /><br />";
}
echo '</script>';
}
Recording counts are done correctly, but I can not make the popup appear in any way.

try this. Hope this help you.
$sql = "SELECT * FROM pt_locations WHERE country = ('country') AND
location = ('location')";
$result = $conn->query($sql);
$rowcount=mysqli_num_rows($result);
$message = "Records found: " . $rowcount;
if ($rowcount > 1) {
echo '<script language="javascript">';
echo 'alert("'.$message.'")';
echo '</script>';
while($val=mysqli_fetch_assoc($result)){
$id_country = $val["country"] ;
$id_code = $val["code"] ;
$id_location = $val["location"] ;
$id_latitude = $val["latitude"] ;
$id_longitude = $val["longitude"] ;
echo "<table border='1' cellpadding='5'>";
echo "<tr>";
echo "<td><i><strong>ID Code</strong></i></td><td>";
echo $id_code."</td>";
echo "<td><i><strong>Country</strong></i></td><td>";
echo $id_country."</td>";
echo "<td><i><strong>Code</strong></i></td><td>";
echo $code."</td>";
echo "<td><i><strong>Location</strong></i></td><td>";
echo $id_location."</td>";
echo "<td><i><strong>Latitude</strong></i></td><td>";
echo $id_latitude."</td>";
echo "<td><i><strong>Longitude</strong></i></td><td>";
echo $id_longitude."</td>";
echo "</tr>";
echo "</table><br /><br />";
}
}

There are some errors, because for logic you must put the alert at the end of the table complete, just for logic and after you put alert something without brakets and you open a script before the foreach loop and after the foreach loop you close the script, this is absolutley wrong, another error is in the $message, you are using br inside an alert javascript that isn't recognize as html but just like characters at the least you can use unicode \n\t not br, i used also a setTimeout,but works also without setTimeout.
Sometimes can result essential use javascript injection inside the php for example to autofill of some forms and input select or to call a change event from external compilation of other application that pass variables in get and need to autofill a form, but i think in this case is not necessary do a javascript injection you can print the total Records just in the page, btw...
The code under works
Bye
$message = "Records found: " . $rowcount." \\n\t\\n\t";
if ($rowcount > 1) {
foreach($result as $val){
//var_dump($val);
$id_country = $val["country"] ;
$id_code = $val["code"] ;
$id_location = $val["location"] ;
$id_latitude = $val["latitude"] ;
$id_longitude = $val["longitude"] ;
echo "<table border='1' cellpadding='5'>";
echo "<tr>";
echo "<td><i><strong>ID Code</strong></i></td><td>";
echo $id_code."</td>";
echo "<td><i><strong>Country</strong></i></td><td>";
echo $id_country."</td>";
echo "<td><i><strong>Code</strong></i></td><td>";
echo $code."</td>";
echo "<td><i><strong>Location</strong></i></td><td>";
echo $id_location."</td>";
echo "<td><i><strong>Latitude</strong></i></td><td>";
echo $id_latitude."</td>";
echo "<td><i><strong>Longitude</strong></i></td><td>";
echo $id_longitude."</td>";
echo "</tr>";
echo "</table><br /><br />";
}
$jvsVar = "<script type='text/javascript'>;setTimeout(function(){alert('$message');},100)</script>";
echo $jvsVar;
}

display php array in javascript [duplicate]

This question already has answers here:
Pass a PHP string to a JavaScript variable (and escape newlines) [duplicate]
(14 answers)
Closed 5 years ago.
I like to display php array in javascript, but in specific element with id.
below is my code which shows what I want to do.
<?php function ogolne_informacje(){
global $mypod;?>
<strong><?php echo 'Pokój: '?></strong><?php echo $mypod->display('room')."<br />";?>
<strong><?php echo 'Email: '?></strong><?php echo $mypod->display('user_email')."<br />";?>
<strong><?php echo 'Telefon: '?></strong><?php echo $mypod->display('phone')."<br />"; }?>
<?php $i =0;
while ( $mypod->fetch() ) :{
ob_start();
ogolne_informacje();
$output[$i] = ob_get_clean();
$i++;
} endwhile;?>
<div id="test"></div>
<script>
var out = <?php echo $output; ?>;
$(document).ready(function () {
$('#test').html(out.toString());
});
</script>
How can I do that?
Thanks!

You can't loop like that, you need to loop the PHP array and push into javascript array:
<script type="text/javascript" language="javascript">
var pausecontent = new Array();
<?php while ( $mypod->fetch() ) :{
ob_start();
ogolne_informacje();
?>
pausecontent.push('<?php echo ob_get_clean(); ?>');
<?php } ?>
</script>

Empty jQuery Autocomplete Array in Firefox and Chrome - Works in Safari

My php invoicing system uses jQuery autocomplete to lookup a customer's name from my database. The layout of the pages is like this:
invoice.php - contains the variable 'customers' and the php database select script
invoice.js - this contains the jQuery on focus command
In Safari everything works fine. I have used the console to see the variables logged - example (CUSTOMERS – ["Paul Smith"] (1))
But in Chrome and Firefox the console shows: "CUSTOMERS" Array [ ]
My code for invoice.php:
var arr_customers = new Array();
<?php $result = mysql_query("select * from customer where breaker='".$_SESSION['breaker_id']."'");?>
<?php $str = ""; $i = 0; while ($row = mysql_fetch_array($result)) { ?>
arr_customers[<?php echo $i;?>] = new Array();
arr_customers[<?php echo $i;?>][0] = "<?php echo $row['customer_name']; ?>";
arr_customers[<?php echo $i;?>][1] = "<?php echo $row['customer_code']; ?>";
arr_customers[<?php echo $i;?>][2] = "<?php echo $row['address']; ?>";
arr_customers[<?php echo $i;?>][3] = "<?php echo $row['uid']; ?>";
<?php if ($i == 0) {
$str = "'" . $row['customer_name'] . "'";
} else {
$str = $str . ",'" . $row['customer_name'] . "'";
}?>
<?php $i++;
} ?>
var customers =<?php echo ("[" . $str . "]") ?>;
and for the invoice.js:
jQuery(document).ready(function($) {
$("#customer_name").on('focus', function() {
console.log("CUSTOMERS", customers);
$( "#customer_name" ).autocomplete({
source: customers
});
});
});
I know I should be using prepared statements as well!

Change value of html div using javascript in php foreach

I am running a foreach loop and I want to be able to change the content and class of the affected div elements.
foreach ($fields as $key => $value) { ?>
<script type="text/javascript">
document.getElementById('<?php echo $key ?>').innerHTML = '<?php echo $value ?>';
</script>
<?php } ?>

foreach ($fields as $key => $value) { ?>
<script type="text/javascript">
document.getElementById('<?php echo $key ?>').innerHTML = '<?php echo $value ?>';
</script>
you better use it like this .
<script>
<?php foreach ($fields as $key=>$value){ ?>
document.getElementById("<?php echo $key; ?>").innerHTML = "<?php echo $value; ?>";
<?php } ?>
</script>
and make sure you have all correspoinding elements with the same id as $key in this script for example.
<?php foreach($fields as $key=>$value){ ?>
<div id="<?php echo $key; ?>" ></div>
<?php } ?>
Regards

You may use only one part...
server-side with PHP and more tempting
client-side with Javascript
For the last approach, it could be okay to store / request the array as an JavaScript array, or json object and iterate it / update the existing elements during a loop after the site has been loaded.
A mixture of both may lead to a non-maintainable source and more render and execution time as expected.

I have not got what you actually want, But lets with this code. It may help you...
<script type="text/javascript">
$( document ).ready(function() {
<?php
foreach ($fields as $key => $value) {
?>
document.getElementById('<?php echo $key ?>').innerHTML = '<?php echo $value ?>';
<?php
}
?>
});
</script>

How to alert PHP value in JavaScript?

<script type="text/javascript">
var jvalue = 'this is javascript value';
<?php
$abc = "<script>document.write(jvalue)</script>" ?>
</script>
<?php echo 'php_'.$abc; ?>
<script type="text/javascript">
var test = "<?php echo $abc; ?>";
</script>
<?php
echo '<script language="javascript">';
echo 'alert(test)';
echo '</script>';
?>
How to alert test variable, which contains PHP value?
I would like to get the PHP value in javascript, for further execution in my project.

try this code
<?php
echo '<script language="javascript">alert("'.$test.'"); </script>';
?>
this is updated code for you using javascript and PHP
<?php
$user = "rebel";
echo '<script> var name = "'.$user.'";
alert(name);</script>';
?>
This is the third code for you if this does not work then you have other problem
<?php
$abc= "Hello";
?>
<script type="text/javascript">
var test="<?php echo $abc; ?>";
</script>
<?php
echo '<script language="javascript">';
echo 'alert(test)';
echo '</script>';
?>

why are you assigning the variable to a javascript variable and then echoing that? sounds like extra work to me...
echo 'alert("' . $abc . '");';

Your code is not so clear, i think you want something like this:
<?php
$test = "hi there!";
echo '<script type="text/javascript">';
echo 'alert("'.$test.'")';
echo '</script>';
?>

var test="<?php echo $abc; ?>"
<script language="javascript">alert(test); </script>

If you want to alert the value of $abc, you need to escape the slash in the following line with a backslash, like this.
<?php $abc = "<script>document.write(jvalue)<\/script>" ?>
You also need to remove this line (or escape the < and the > in $abc). If you don't, the script tags will mess up the rendered html code.
<?php echo 'php_'.$abc; ?>
