badeand Posted January 9, 2012 Share Posted January 9, 2012 Hi, Could anyone help me code this so it dosen´t have use the dropdown list to select databases? My hosting service does only provide me with one database, so i do not have access to run the mysql query "Show databases". And i´m having problems getting the logic of coding this so i always select the database i already have predefined. I hope someone could help me with this, it would me much appreciated. The part that i have issues with is this. Below this, the complete code for this file is uploaded. $query = "show databases;"; $result = mysql_query($query); $database_cmb_names = ''; //get the default value if(isset($database_name)) $default_db=$database_name; else $default_db=@$_SESSION['db']; while ($row = mysql_fetch_row($result)) { if($default_db==$row[0]) $database_cmb_names .= "<option selected>"; else $database_cmb_names .= "<option >"; $database_cmb_names .= $row[0]; $database_cmb_names .= "</option>\r\n"; } } } If i need to upload the rest of the files for this script, let me now. <?php session_start(); error_reporting(E_ERROR | E_PARSE); //get form variables //buttons if(isset($_POST['btn_cont_x'])) $btn_continue = $_POST['btn_cont_x']; if(isset($_POST['btn_back_x'])) $btn_back = $_POST['btn_back_x']; if(isset($_POST['btn_connect_x'])) $btn_connect = $_POST['btn_connect_x']; //input fields if(isset($_POST['host_name'])) $host_name = $_POST['host_name']; if(isset($_POST['user_name'])) $user_name = $_POST['user_name']; if(isset($_POST['password'])) $password = $_POST['password']; if(isset($_POST['database_name'])) $database_name = $_POST['database_name']; if(isset($_POST['data_source'])) $data_source = $_POST['data_source']; //vars $is_form_valid = 1; $page_errors = ''; //check which button was clicked if(!empty($btn_continue)) //continue { if(empty($host_name)) { $page_errors = "* Please enter host name."; $is_form_valid = 0; } if(empty($user_name)) { if(!empty($page_errors)) $page_errors .= "<br>"; $page_errors .= "* Please enter user name." ; $is_form_valid = 0; } if(empty($database_name)) { if(!empty($page_errors)) $page_errors .= "<br>"; $page_errors .="* Please select database name."; $is_form_valid = 0; } if($is_form_valid) { $_SESSION['db'] = $database_name; $_SESSION['datasource'] = $data_source; // table or query if($data_source =='sql') //sql query selected { header("Location:step_3_sql.php"); } else //table selected { header("Location:step_3.php"); } } } else if(!empty($btn_back)) //back { header("Location:step_1.php"); exit; } else if(!empty($btn_connect) || !empty($_SESSION['host'])) //connect or back { if(!empty($_SESSION['host']) && empty($btn_connect)) //back { $host_name = $_SESSION['host']; $user_name = $_SESSION['user']; $password = $_SESSION['pass']; } if(empty($host_name)) { $form_errors = "* Please enter host name."; $is_form_valid = 0; } if(empty($user_name)) { $page_errors .= "* Please enter user name." ; $is_form_valid = 0; } if($is_form_valid ==1) { if(@!mysql_connect($host_name, $user_name, $password)) { if(!empty($page_errors)) { $page_errors .="<br>"; } $page_errors .= "* Unable to connect. Please enter valid host name, user name and password"; } else { // save data in the sessions if(!empty($btn_connect)) // only in case of connect { $_SESSION['host'] = $host_name; $_SESSION['user'] = $user_name; $_SESSION['pass'] = $password; } $query = "show databases;"; $result = mysql_query($query); $database_cmb_names = ''; //get the default value if(isset($database_name)) $default_db=$database_name; else $default_db=@$_SESSION['db']; while ($row = mysql_fetch_row($result)) { if($default_db==$row[0]) $database_cmb_names .= "<option selected>"; else $database_cmb_names .= "<option >"; $database_cmb_names .= $row[0]; $database_cmb_names .= "</option>\r\n"; } } } } //functions section //get default valu for each form field function get_default_value($var) { $s_var = $var; if($var =='user_name') $s_var = 'user'; if($var=='password') $s_var = 'pass'; if($var=='host_name') $s_var = 'host';
