How to get span text in in php variable?

<span class="cid"></span>
In the above span, i am getting id from .js file. eg., 45 and i want that id in php variable. eg., $cid='45';
I have already tried below code, but i am unable to get id.
<?php echo $cid='<span class="cid"></span>'; ?>
<?php
$str = $cid;
$DOM = new DOMDocument;
$DOM->loadHTML($str);
$items = $DOM->getElementsByTagName('span');
$span_list = array();
for($i = 0; $i < $items->length; $i++) {
$item = $items->item($i);
$span_list[$item->getAttribute('class')] = $item->nodeValue;
}
extract($span_list);
echo $cid;
?>

try this one add span text in php code to get the span value in variable
<?php
$value = '<span class="cid"></span>';
?>
echo $value

Please try the below code and check at your end you can get class value in the array.
Second time Update code
<?php
echo $cid='<span class="cid">45</span>';
?>
<?php
$str = $cid;
$DOM = new DOMDocument;
$DOM->loadHTML($str);
$items = $DOM->getElementsByTagName('span');
$span_list = '';
for($i = 0; $i < $items->length; $i++) {
$item = $items->item($i);
if($item->getAttribute('class') == 'cid'){
$span_list = $item->nodeValue;
}
}
echo $span_list;
?>
Code for multiple span tags and get single value from that span list array.
<?php
$cid='<span class="cid">45</span> <span class="cid">48</span>';
?>
<?php
$str = $cid;
$DOM = new DOMDocument;
$DOM->loadHTML($str);
$items = $DOM->getElementsByTagName('span');
$span_list = array();
for($i = 0; $i < $items->length; $i++) {
$item = $items->item($i);
if($item->getAttribute('class') == 'cid'){
$span_list[] = $item->nodeValue;
}
}
//get the each value for multiple span tag
foreach ($span_list as $key => $value) {
echo $value;
echo '<br/>';
}
?>

Add an AJAX code to pass it to PHP
$.ajax({
url: 'your_php_file.php',
method: 'POST',
data: {cid: $('.cid')[0].innerText},
success: function(result){
console.log(result);
}
})
And in your PHP file.
You can just use strip_tags
echo strip_tags($_POST['cid']);

Using variable on php to create another variable in JS

I'm having a hard time getting the value of a specific variable in php to use in js. This is my code in php:
<?php
require("connection.php");
$sql_cmd = "SELECT * FROM tbstatus";
$stmt = $con->prepare($sql_cmd);
$stmt->execute();
echo "<h2>STATUS OF THE BABY</h2>";
while ($result = $stmt->fetch(PDO::FETCH_ASSOC)) {
echo "<h4>" . $result['status'] . "</h4>";
}
?>
I want to get the value of this ($result['status']) and pass it on the variable pos in js. This is my js code:
setInterval(function() {
$("#position").load('refresh.php');
notif();
}, 1000);
function notif() {
var pos = $('PHP VARIABLE HERE').val();
alert(pos);
}
Thanks for your help.

The easiest way is to output it to javascript directly:
?>
<script type="text/javascript">
window.MY_PHP_VAR = <?php echo json_encode($myPhpVar); ?>;
</script>
...
window.MY_PHP_VAR now contains your php variable

if your javascript code is on same page where the result is comming then you can use this
var pos = `<?php echo $result['status'] ?>`;
var pos = `<?= $result['status'] ?>`;

===============
// refresh.php
===============
<?php
require("connection.php");
$sql_cmd = "SELECT * FROM tbstatus";
$stmt = $con->prepare($sql_cmd);
$stmt->execute();
echo "<h2>STATUS OF THE BABY</h2>";
while ($result = $stmt->fetch(PDO::FETCH_ASSOC)) {
echo "<h4>" . $result['status'] . "</h4>";
echo "<script> alert('". $result['status'] ."'); </script>";
/* If the $result['status'] is 'success' the above line will be converted to:
echo "<script> alert('success'); </script>";
*/
}
?>
so, every time the refresh.php loads, the script is going to get executed.
However, I suggest you to assign a id or class attribute to your h4 where you are echoing your status and access the value using the selectors in the javascript.

you could try giving an id or class to the status.
then in JavaScript you could then get the value of the id or class.
PHP
<?php
require("connection.php");
$sql_cmd = "SELECT * FROM tbstatus";
$stmt = $con->prepare($sql_cmd);
$stmt->execute();
echo "<h2>STATUS OF THE BABY</h2>";
while ($result = $stmt->fetch(PDO::FETCH_ASSOC)) {
echo '<h4> <span class="status">' . $result['status'] . '</span></h4>';
}
?>
JavaScript
var oldStatus = '';
setInterval(function() {
$("#position").load('refresh.php');
notif();
}, 1000);
function notif() {
// note that since we used a class, you will get the value of the first element only.
var pos = $('.status').text(); // use .text() instead of .val()
if (pos.toLowerCase() == 'out' && pos != oldStatus){
oldStatus = pos;
alert(pos);
}
}

How to display values in JS from a PHP array that was posted from jQuery

I have a button called rename that when pushed, executes in jQuery a rename.php file. Inside that php file the program selects data from a mysql, creates an array with that data, and processes an array in to json_encode($array);. How can I then get that json encoded array and echo it out into javascript?
I'm trying to echo the array out so that javascript displays my images src's.
This is my second line of ajax so I just wrote the javascript out as if it were php because I'm not sure of the commands or structure in js.
$.ajax
(
{
url:"test4.php",
type: "GET",
data: $('form').serialize(),
success:function(result)
{
/*alert(result);*/
document.getElementById("images_to_rename").innerHTML = foreach(jArray as array_values)
{
"<img src=\""array_values['original_path']"/"array_values['media']"/>";
}
}
}
);
and my jQuery php file:
<?php
include 'db/mysqli_connect.php';
$username = "slick";
if(empty($_GET['image_name']))
{
echo '<div class="refto" id="refto">image_name is empty</div>';
}
else
{
echo '<div class="refto" id="refto">image_name is not empty</div>';
foreach($_GET['image_name'] as $rowid_rename)
{
//echo '<br><p class="colourful">rowid_refto: '.$rowid_refto.'</p><br>';
$active = 1;
$command = "Rename";
$stmt = $mysqli->prepare("UPDATE ".$username." SET active=?, command=? WHERE rowid=?");
$stmt->bind_param("isi", $active, $command, $rowid_rename);
$stmt->execute();
$stmt->close();
}
//go to database, get parameters of sort
$command = "Rename";
$active = 1;
$stmt = $mysqli->prepare("SELECT original_path, media FROM " . $username . " WHERE active=? and command=?");
$stmt->bind_param("is", $active, $command);
$stmt->execute();
$result = $stmt->get_result();
while($row = $result->fetch_assoc())
{
$arri[] = $row;
}
foreach($arri as $rows) //put them into workable variables
{
$rowt = $rows['original_path'];
$rowy = $rows['media'];
//echo 'rows[\'original_path\'] = '.$rows['original_path'].''.$rows['media'].'';
}
$stmt->close();
echo json_encode($arri);
?>
<script type="text/javascript">
var jArray= <?php echo json_encode($arri); ?>;
</script>
<?php
}
echo "something2";
?>
My PHP file is a jQuery url:"test4.php", type: "GET", and is not the main file. The main file is called main.php and the test4.php is something that's called in jQuery when the user clicks on rename.
Somebody suggested console log so here's what chrome says:
<div class="refto" id="refto">image_name is not empty</div>[{"original_path":"Downloads","media":"shorter.jpg"},{"original_path":"Album 2","media":"balls.jpg"}] <script type="text/javascript">
var jArray= [{"original_path":"Downloads","media":"shorter.jpg"},{"original_path":"Album 2","media":"balls.jpg"}];
</script>
something2

Your ajax php file isn't render in browser, then the variable jArray is undefined. With your case, let return php file to json and you can get it as variable in result.
<?php
include 'db/mysqli_connect.php';
$username = "slick";
if (empty($_GET['image_name'])) {
//echo '<div class="refto" id="refto">image_name is empty</div>';
} else {
//echo '<div class="refto" id="refto">image_name is not empty</div>';
foreach ($_GET['image_name'] as $rowid_rename) {
//echo '<br><p class="colourful">rowid_refto: '.$rowid_refto.'</p><br>';
$active = 1;
$command = "Rename";
$stmt = $mysqli->prepare("UPDATE " . $username . " SET active=?, command=? WHERE rowid=?");
$stmt->bind_param("isi", $active, $command, $rowid_rename);
$stmt->execute();
$stmt->close();
}
//go to database, get parameters of sort
$command = "Rename";
$active = 1;
$stmt = $mysqli->prepare("SELECT original_path, media FROM " . $username . " WHERE active=? and command=?");
$stmt->bind_param("is", $active, $command);
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
$arri[] = $row;
}
foreach ($arri as $rows) { //put them into workable variables
$rowt = $rows['original_path'];
$rowy = $rows['media'];
//echo 'rows[\'original_path\'] = '.$rows['original_path'].''.$rows['media'].'';
}
$stmt->close();
echo json_encode($arri);
//stop render here
die();
}
?>
php file need return only json string. Then we'll get result as json variable in javascript.
And Js:
$.ajax
(
{
url:"test4.php",
type: "GET",
data: $('form').serialize(),
success:function(result)
{
var jArray = JSON.parse(result);
/*alert(result);*/
var txt = "";
jArray.forEach(function(array_values){
txt += `<img src=\""array_values.original_path."/"array_values.media"/>`;
})
document.getElementById("images_to_rename").innerHTML = txt;
}
}
);

Have description have a limit of the amount of characters on the page. PHP

Okay, so I'm working on a PHP site, I have descriptions of the product under the image, what I'm need to do is limit the amount of characters on the page and add a click here or.. For the viewers to be directed to that products page to see the full description. FYI very new to PHP, here is what I have so far. So question is do I use PHP or javascript or both and how do I do that ?
<?php
// Include need php scripts
require_once ("Includes/simplecms-config.php");
require_once ("Includes/connectDB.php");
include ("Includes/header.php");
if (!empty($_GET['cat'])) {
$category = $_GET['cat'];
$query = mysqli_query($db, "SELECT * FROM products WHERE category = '".$category."'");
} else {
$query = mysqli_query($db, "SELECT * FROM products");
}
if (!$query) {
die('Database query failed: ' . $query->error);
}
?>
<section>
<div id="productList">
<?php
$row_count = mysqli_num_rows($query);
if ($row_count == 0) {
echo '<p style="color:red">There are no images uploaded for this category</p>';
} elseif ($query) {
while($products = mysqli_fetch_array($query)){
$file = $products['image'];
$product_name = $products['product'];
$image_id = $products['id'];
$price = $products['price'];
$desc = $products['description'];
echo '<div class="image_container">';
echo '<a href="viewProduct.php?id=' . $image_id . '"><p><img src="Images/products/'.$file.'" alt="'.$product_name.'" height="250" /></p>';
echo $product_name . "</a><br>$" . $price . "<br>" . $desc;
echo '</div>';
if (is_admin()){
echo "<a href='deleteproduct.php'><button>delete</button></a>";
}
}
} else {
die('There was a problem with the query: ' .$query->error);
}
mysqli_free_result($query);
?>
</div>
</section>
<?php include ("Includes/footer.php"); ?>

using strlen and substr we can achieve this
$length = 150
$x = 'string';
if(strlen($x)<=$length)
{
echo $x;
}
else
{
$y=substr($x,0,$length) . '...';
echo $y;
}
