PHP Looped Array, jquery to print each id value

So far I have managed that when a button is clicked it will print all values within the array. I need it to be smarter and only print the value of the element clicked.
<?php
$Arr_shoppingList = array(
array("Volvo",22,18,0),
array("BMW",15,13,1),
array("Saab",5,2,2),
array("Land Rover",17,15,3)
);
//Looped through array and printed values
foreach ($Arr_shoppingList as $value) {
echo "<div class='ColumnRow Spacing Color2 Border'>";
echo "<h1> $value[0] </h1> <br>";
echo "<p>'MPG'. $value[1]</p> <br>";
echo "<p>'Stock' . $value[2]</p> <br>";
echo "<form method='GET'>";
echo "<button class='Border' type='submit' id='$value[0]' class='Button'> $value[0]
</button>";
echo "</form>";
echo "</div>";
}
?>
<script>
$('button').on('click', function (event) {
event.preventDefault()
$('button').each(function(index, value){
console.log(value.id)
})
});
</script>
EDIT: The first section has been completed many thanks, but similarly, but I also need the stock and MPG values to also be targeted, how would I go about incorporating that into this code? this is part of a checkout basket I'm attempting to create.

You can use event.target.id to get the id of the clicked element
<?php
$Arr_shoppingList = array(
array("Volvo",22,18,0),
array("BMW",15,13,1),
array("Saab",5,2,2),
array("Land Rover",17,15,3)
);
//Looped through array and printed values
foreach ($Arr_shoppingList as $value) {
echo "<div class='ColumnRow Spacing Color2 Border'>";
echo "<h1> $value[0] </h1> <br>";
echo "<p>'MPG'. $value[1]</p> <br>";
echo "<p>'Stock' . $value[2]</p> <br>";
echo "<form method='GET'>";
echo "<button class='Border' type='submit' id='$value[0]' class='Button'> $value[0]
</button>";
echo "</form>";
echo "</div>";
}
?>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
$('button').on('click', function (event) {
event.preventDefault()
console.log(event.target.id);
});
</script>

Trying to use JavaScript to calculate total booking price for selected seats using php pdo?

I am trying to use JavaScript to calculate total price for the tickets which are selected by using the checkbox. The result is should be shown in a alert window by clicking on the check button which invokes the JavaScript function. But when I click the button nothing happens. I don't even get any error message. I am a beginner so please if anyone can help me, I will be extremely thankful.
<?php foreach ($res as $row): ?>
<form action="book.php" method="get">
<tr><td><?php echo $row['RowNumber']; ?></td><td><?php echo $row['Price']; ?></td>
<td><input type="checkbox" type="hidden" name="myForm[<?php echo $row['RowNumber']; ?>][row]" id="row" value="<?php echo $row['RowNumber']; ?>"></input></td></tr>
<input type="hidden" name="myForm[<?php echo $row['RowNumber']; ?>][price]" id="price" value="<?php echo $row['Price']; ?>"></input>
</form>
<?php endforeach; ?>
</table>
<form action='book.php' method='get'>
Enter Email:<input type='text' name='name'></form>
<script>
function summary() {
var total = 0.0;
var seats = document.getElementById("row").value;
for(i = 1; i <= document.getElementById("row").value; i++) {
if(document.getElementId("row").checked) {
total = total + parseFloat(document.getElementById("price").innerHTML);
}
}
return total;
alert("Price of seats =" + total);
}
</script>
<input type="button" onclick="summary()" value="check">
<?php

You're returning before calling the alert, which means you never get to the alert itself. Remove the return total line.

This is a very common problem.All we have face atleast once.you should use Chrome istead of firefox or internet explorer.close your webpage and restart again.
return total should be after alertbox.
thankx.

You can try this sample
<form action="book.php" method="get">
<table>
<?php foreach ($res as $row): ?>
<tr data-rownumber="<?php echo $row['RowNumber']; ?>">
<td><?php echo $row['RowNumber']; ?></td>
<td><?php echo $row['Price']; ?></td>
<td>
<input type="checkbox" name="myForm[<?php echo $row['RowNumber']; ?>][row]" id="row-<?php echo $row['RowNumber']; ?>" value="<?php echo $row['RowNumber']; ?>" onclick="summary()" />
<input type="hidden" name="myForm[<?php echo $row['RowNumber']; ?>][price]" id="price-<?php echo $row['RowNumber']; ?>" value="<?php echo $row['Price']; ?>" />
</td>
</tr>
<?php endforeach; ?>
</table>
</form>
<form action='book.php' method='get'>
Enter Email:<input type='text' name='name'>
</form>
<script>
function summary() {
var total = 0.0;
var table = document.getElementById('items-table');
var rows = table.getElementsByTagName('tr');
for (var i = 0; i < rows.length; i++) {
var row = rows[i];
var rowNumber = row.getAttribute('data-rownumber');
var isChecked = document.getElementById('row-' + rowNumber).checked;
if (isChecked) {
var price = parseFloat(document.getElementById('price-' + rowNumber).value);
total += price;
}
}
alert("Price of seats = " + total);
return total;
}
</script>
<input type="button" onclick="summary()" value="check">

Get input before submitting to insert into action url

Im trying to get a value of an input into my buttons action url before the button is pushed.
I need to get the value of:
id="qty<?php echo $i;?>"
Into where it says:
<?php echo VALUE OF $qtyforaction; ?>
My Code is:
<?php $i = $_product->getId();?>
<form action="<?php echo $this->helper('checkout/cart')->getAddUrl($_product); ?>" method="post" id="product_addtocart_form_<?php echo $_product->getId()?>"<?php if($_product->getOptions()): ?> enctype="multipart/form-data"<?php endif; ?>>
<input type="text" name="qty" id="qty<?php echo $i;?>" maxlength="12" value="1" title="Qty" class="cartnum" />
<?php $qtyforaction = 'qty'.$i; ?>
<?php echo $qtyforaction; ?>
<button type="button" class="addtocartbutton button btn-cart" onclick="setLocation('<?php echo $this->helper('checkout/cart')->getAddUrl($_product); ?>qty/<?php echo VALUE OF $qtyforaction; ?>')" ><span><span>Order Again</span></span></button>
</form>
Would I have to use javascript to get it into the url string? My javascript is a bit ropey, would something like this work?
<script type="text/javascript">
var something= document.getElementById('<?php echo $qtyforaction;?>');
</script>

</div>
</form>
</div>
<?php
echo "<div class='previous-clear'></div>";
echo "</li>";
}
}
}
?>

You need to get the value of the id attribute:
var x = document.getElementsByTagName("input")[0].getAttribute("id");
But how do you plan on using PHP to echo out this variable if PHP is loaded and done with before Javascript even comes into play? You could use Javascript though to display this variable on the page if that's all you needed.
If you had something in your HTML to target, you could do it like this:
document.getElementById("result").innerHTML = x;
But anyways, get the action attribute value...
var y = document.getElementsByTagName("form")[0].getAttribute("action");
Then set the action attribute to this + the qty...
document.getElementsByTagName("form")[0].setAttribute("action", x + y);
That should work for you, if not, try wrapping x + y in additional parentheses...("action", (x + y));

I want to remove particular row from table when i click on REMOVE link displaying in a same row, how to achive this?
link is ok or should i have to use button.If any one write some code may helpfull as am new webie...
Thanks in advance.

$('i').click(function(){
$(this).parent('a').parent('td').parent('tr').remove();
});

The row is deleted but as clicking makes you follow the link, it's immediately restored when the page is refreshed.
Add return false; or event.preventDefault(); at the end of the callback to prevent the default behavior :
$(document).ready(function() {
$("#favoriteFoodTable .deleteLink").on("click",function() {
var tr = $(this).closest('tr');
tr.css("background-color","#FF3700");
tr.fadeOut(400, function(){
tr.remove();
});
return false;
});
});

Passing an id to a PHP script using jQuery/Ajax

and this the PHP script that the code above redirect to.
<?php

echo "<td>".$row['articlemore'] . "</td>";
echo "</tr>";
echo "</table>";
//echo "</div>";
?>
I'm having this kind of error:
Undefined index: id in C:\xampp\htdocs\ckeditor\samples\postview.php on line 4

You need to check if argument "id" is passed to the php script first
<?php
include 'connection.php';
if( (isset($_GET['id'])) && ($_GET['id'] != '') ){ //check if the argument "id" is passed to the script
$id=$_GET['id'];
echo $id;
$sql="SELECT * FROM blog WHERE articleid='$id'";
$result=mysqli_query($link, $sql);
echo "<table>";
$row=mysqli_fetch_array($result);
echo "<tr>";
echo "<td>".$row['articletitle'] . "</td>";
echo "<td><img src='image.php?id=$row[articleid]' width='200' height='200' /><br/></td>";
echo "<td>".$row['articlemore'] . "</td>";
echo "</tr>";
echo "</table>";
//echo "</div>";
}
?>

Not so much an answer to your question, but probably a good suggestion to make your code a lot cleaner- try using PHP Alternative Syntax and moving in and out of PHP to make your HTML clean.
<?php while($row=mysqli_fetch_array($result)):?>
<tr class="record">';
<td><?php echo $row['articletitle'];?>
<td>Edit
<input type='hidden' name='id' value='<?php echo $row['articleid'];?>'></td>
<td>
<div align="center">
Delete
</div>
</td>
</tr>
<?php endwhile;?>
<form method="post" id="myForm" action="postview.php">
<input type="hidden" name="myID">
</form>

$sql="SELECT * FROM blog WHERE articleid='".$id."'";
try this line

That isnt an error, but a notice, which is lowlevel It simple means $_GET['id'] doesnt hav a value
echo $example['something']; // will give undefined index notice
$example['something'] = 'abc';
echo $example['something']; // No notices
Your website should be domain.ext/?id=123, if not, this notice will show.
