Getting ID from a PHP script and inplement in a URL-CodePudding

I want to pass in the URL an ID from the following PHP script:

<tbody>
    <?php
    foreach ($EditProductInformations as $EditProductInformation) :
    ?>
    <tr>
        <td colspan="2">
            <div >
                <div >
                    <select  name="produkt[]">
                            <?php foreach ($resultsProdukt as $resultp) { ?>
                                <option value="<?= $resultp["ProduktID"] ?>" <?php if($resultp["ProduktID"] == $EditProductInformation["ProduktID"]): ?>selected<?php endif; ?>><?= $resultp["produktname"] ?></option>
                            <?php } ?>
                    </select>
                </div>
                <div > <input type="text"  placeholder="https://" name="url" value="<?= $EditProductInformation['url']; ?>"></div>
                <p> <div >  <a onclick="confirmDeleting(id)"  href="#" id="<?= $EditProductInformation['ID'] ?>"><i id="produktDel" ></i>  </a> </div> </p> 
            </div>
            <br>
        </td>
    </tr>
    <?php endforeach ?>
</tbody>

this so my js script so far:

    function confirmDeleting(elemen) {
        let confirmDeleting = confirm("are you sure, you want to delete?");
        if (confirmDeleting) {
            console.log(elemen);
            window.location.href="formprocess.php?dfID="   elemen.dataset.id;
            }
        }

My URL is good so far, but I cant reach the ID

"formprocess.php?dfID=undefined"

is the URL but I want that it will be

"formprocess.php?dfID=144"

Thanks in advance

CodePudding user response：

You don't have any dataset attribute, and all attribute value of element will be in string, so better if you have custom attribute of your element
Something like this:

<a onclick="confirmDeleting(this)" data-id="<?php echo $resultp[\"ProduktID\"]; ?>"  href="#">

And you can access that attribute by:

elemen.getAttribute("data-id");

Also if you are using JQuery you can do it like this:

$(elemen).data("id");

CodePudding user response：

Instead of passing 'this' as a parameter to the confirmDeleting() function, you can give it as a parameter directly the ID of the product concerned. So the code will be:

<a onclick="confirmDeleting(<?php echo $resultp["ProductID"] ?>)"  ><i id="productDel" ></i></a>

Then you will only have to retrieve the ID parameter in your JS function

function confirmDeleting(ProductID) {
let confirmDeleting = confirm("are you sure, you want to delete?");
if (confirmDeleting) {
    console.log(ProductID);
    window.location.href="formprocess.php?dfID="   ProductID;
    }
}
