Tried over 5 hours to figure out</strong></p> <p>Anyway I have the following:</p> <pre><code>class RecoverPas{ private $mysqli; public function __construct() { $this-&gt;newMessage(); //Allow new object access to default Error Messages. $this-&gt;deleteOldCodes(); //Delete reset codes older that a certain interval. $this-&gt;mysqli = new mysqli(DB_SERVER, DB_USER, DB_PASS, DB_NAME); $this-&gt;mysqli-&gt;set_charset("utf8"); if($this-&gt;mysqli === false) { user_error("Unable to connect to database via mysqli."); return false; } } public function deleteOldCodes(){ $query_deloldcodes = mysqli_query($this-&gt;mysqli, "delete FROM activereset WHERE date &lt; DATE_SUB(CURDATE(), INTERVAL '".$this-&gt;deloldcodeint."' DAY)"); if ( false===$query_deloldcodes ) { printf("error: %s\n", mysqli_error($this-&gt;mysqli)); } } } $forgotpass = new RecoverPas(); </code></pre> <p>About the mysqli connect , the db info is ok I defined the db info in other php file, and this mysqli conenct work in other class perfect, also I test if the defines works here and they are defined here too.</p> <p>As you see I tried to print the errors but no I keep getting only this :</p> <pre><code>Warning: mysqli_query() expects parameter 1 to be mysqli, null given in line 506 </code></pre> <p>Line 506 is <code>public function deleteOldCodes(){</code> that i put above , I dont get mysqli error so its seem That there is a conenction, and i try to printf the mysqli error and not working either.</p> <p>So what wrong here?</p>

    1. COYou call `deleteOldCodes` function before `$this->mysqli` is defined, so it is `null`

    2. COYou're calling `$this->deleteOldCodes();` (which uses `$this->mysqli`) **before** you setup `$this->mysqli`

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.

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