    <p>I am working freelance on a website that website hacked 3 times before my working.</p> <p>I am working now and after some chnges I will upload I use these steps for security. some other help full tips will be appreciated. </p> <p>I thought there is a problem with server because some port was not secure. And I am not able to find and communicate that with server administrator.</p> <p>I want to make completely secure site from hack:</p> <p>I use these two functions for prevent with sql injections.</p> <pre><code>function escape($string) { if(get_magic_quotes_gpc()) $string = stripslashes($string); return mysql_real_escape_string($string); } </code></pre> <p>And some time use: </p> <pre><code>function remove_spc_chr($str){ $str=trim($str); $arr=array('%','$','/','\\','*','+','=','\'','"','#','@','(',')','^','~','`','&amp;', ',',';','\'','?','&lt;','&gt;','!','{','}','[',']'); $str=str_replace($arr,'',$str); $str=strip_tags($str); return $str; } </code></pre> <p>And I use for htaccess security this code:</p> <pre><code>RewriteEngine on Options -Indexes Options

    1. COYou should investigate what "hacked" means. A SQL-injection can typically only enforce access to the database; worst is that they download, remove or add information to the database. An XSS-injection means, the worst scenario is that others can take over a session and log in as admin in the websites "backend". Depending on what your application does, these two allow a hacker to inject code which will be run gaining access to the server. But your problem is much wider then two or three functions.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
