Catalogue product

[Adrien]

Hi all,

 

I create a catalogue page. I'made a few products displayed on it. but I want to create a link from the products to have more details of it.

product1 - product2 ... if I clic on product 1 I can show (in a lightbox) the details of it.

on this moment I do that but don't know how can i create the link for the product.

I think need a _post and a _get but not really how do this.

 

If anyone can help me... =)

$reponse = $bdd->query('SELECT * FROM MYDB LIMIT 200');while ($donnees = $reponse->fetch())
{
?>
<a href="<?php echo $url ?>">
<div class="divGeneral">
<img src='<?php echo $donnees['Image']; ?>' class="imgG" />
<?php
echo '<p> ' . $donnees['Titre'] . $donnees['Edition'] . '</p>';
?>
</div>
</a>
<?php

You would use a querystring parameter to pass the ID of a product to your "details" page. Something like: productDetails.php?productId=123

 

Then, on the productDetails.php page, you just look for $_GET['productId'] and select that product from the database.

 

Make sure you properly escape the $_GET value before you use it in the database.

Thanks for your reply Scootstah,

 

on this moment my problem is not the productDetails.php page but the global catalog page.

 

I need to create a link on each products who you see on the page to go to the product details. 

with a form it's method=post but here I don't know really how can I do it.

 

exemple :

<a href="<?php productDetails.php?productId" ?> method=POST">
echo '<p> ' . $donnees['Titre'] . '-' . $donnees['Edition'] . '</p>';
</a>

I miss something but don't know what...

There is no method="post" for an anchor tag (<a></a>). 

 

href="<?php productDetails.php?productId" ?>  

 

needs to be (assuming your product id column is named Id)

 

 href="productDetails.php?productId=<?php echo $donnees['Id'] ?>"

ok I understand, 

 

If i want to add more information can I dot it ?

href="productDetails.php?productId=<?php echo $donnees['Id','Id2','id3'] ?>"

[Ch0cu3r]

No. Not like that.

 

To pass more than one value in the querystring you separate each key/value pair with an ampersand, eg

filename.php?id=value2&id2=value2&id3=value3

The IDs could also be passed with a delimiter. For example:

<?php
if(isset($_GET['myIDs'])) {
    $_GET['myIDs'] = explode('|', $_GET['myIDs']);
    echo '<pre>' . print_r($_GET['myIDs'], true) . '</pre>';
}
?>
<a href="?myIDs=1|3|4">Test</a>

i'll continue to learn

You actually can assign multiple values to a single parameter, but PHP wants you to mark this parameter with square brackets:

<?php

function html_escape($value, $encoding)
{
    return htmlspecialchars($value, ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML5, $encoding);
}

if (isset($_GET['x']))
{
    echo 'The following values have been passed to the parameter x:<br>';
    foreach ($_GET['x'] as $x)
    {
        echo html_escape($x, 'UTF-8').'<br>';
    }
}

?>
<a href="test.php?x[]=1&x[]=2&x[]=3">Click me</a>

(The brackets should be URL-encoded as %5B and %5D, since they're reserved characters. This is only a demo.)
