wordpress插件将定义的URL重定向到另一个显示权限错误的url选项页面

Question

i was working on a plugin that can find some special url in wordpress page contents and then if matching URL found then change that url automatically to another url like without giving backlink benfit to that site.

for example : if i have defined a site that start with www.site2.com and i wants to redirect this to another site www.site3.com

now pluging will convert url found www.site.com on page to www.site.com/og.php=www.site2.com now if user clicks this url this will be redirected to www.site3.com

after inslalling and activating plugin found urls are converting but when i clicks them getting error "/og.php" file not found

And when i have tried to open option page to add more url or changing some settings on page it's giving me error "you do not have permission to access this page"

below you can check my codes for both pages

CODE FOR OPTION PAGE:

<?php

$location = get_option('siteurl') . '/wp-admin/st_auto_affiliate_links_options.php'; // Form Action URI


// Set a few defaults to get people started and use as examples
add_option('st_aal_before', 'http://www.hammacher.com
http://www.thinkgeek.com
http://www.blogrush.com');

add_option('st_aal_after', 'http://www.dpbolvw.net/j6117p-85-7NPVWPRURNPORVORWO?url=%ENCODED_TARGET%&cm_ven=CJ&cm_cat=1511450&cm_pla=1781363&cm_ite=Hammacher+Schlemmer&sid=%TARGET%

Answer 1

You still have a lonnnnnng way young grasshopper. Your first issue to be solved, is you 'insufficient privileges issue'. Secondly you will want to use the wordpress link for your form action which is : <?php echo str_replace( '%7E', '~', $_SERVER['REQUEST_URI']); ?>

Then, you may want to look into session handling for other various issues that you are bound to run into. See here: http://devondev.com/2012/02/03/using-the-php-session-in-wordpress/

I would share more links, but I know that Google will lead you to the right place. I know this to be true, as I was in the same situation 1 week ago.
