PHP Bulk Delete

PHP Bulk Delete allows multiple or all data to be deleted together

The new php file displays the contents of the database:

<table width= "100%" border= "1" cellpadding= "0" cellspacing= "0" ><tr>    <td><input type= " CheckBox "id=" QX "onclick=" Xuanzhong () "/> Select all </td>    <td> code </td>        <td> name </td >    </tr>        <?phpinclude ("DBDA.class.php"); $db = new Dbda (); $sql = "Select Areacode,areaname from Nation "; $attr = $db->query ($sql); foreach ($attr as $v) {echo" <tr><td><input type= ' checkbox ' name= ' CK [] ' class= ' ck ' value= ' {$v [0]} '/></td>    <td>{$v [0]}</td>        <td>{$v [1]}</td>    </tr> ";}? >    </table>

<?phpclass dbda{public $host = "localhost";p ublic $uid = "root";p ublic $pwd = "";p ublic $dbname = "12345";//Member Method public fu Nction Query ($sql, $type =1) {$db = new mysqli ($this->host, $this->uid, $this->pwd, $this->dbname); $r = $db- >query ($sql), if ($type ==1) {return $r->fetch_all ();} Else{return $r;}}}

　　

Add a Select check box to the table:

<td><input type= "checkbox" id= "QX" onclick= "Xuanzhong ()"/> Select all </td>

　　

<td><input type= ' checkbox ' name= ' ck[] ' class= ' ck ' value= ' {$v [0]} '/></td>

<script type= "Text/javascript" >function Xuanzhong () {//Take the Select state of the All-selected button var zt = document.getElementById ("QX"). checked;//let all of the checkboxes selected below change var ck = document.getelementsbyclassname ("ck"); for (Var i=0;i<ck.length;i++) {if (zt {Ck[i].setattribute ("checked", "checked");} Else{ck[i].removeattribute ("Checked");}}} </script>
