OLD POST

Hi Guys,

I am currently writing a plugin for my client in wordpress. The issue I am having is when a user clicks on edit to change a record I am not sure how to create the admin link to do this.

i.e.

<a href="https://wordpress.stackexchange.com/questions/4677/<?php echo get_bloginfo("url'); ?>/wp-admin/admin.php?page=wpsc_product_seo_details">Edit</a>


function wpsc_product_seo_details()
{
    echo "<h2>Hello</h2>";
}

I know my markup for the tag is probably wrong but I was just testing. Do I need to register a hook to do this.

I am not sure what you are trying to do.

Admin links can be conveniently created with admin_url() function, like this:

$path="admin.php?page=wpsc_product_seo_details";
$url = admin_url($path);
$link = "<a href="https://wordpress.stackexchange.com/questions/4677/{$url}">Edit</a>";
echo $link;

What exactly do you have problem with?
