[英]how to create insert query with multidimensional array in php
This class is working perfectly on single array but when i add multidimensional array dont working.i create the class which automatically get column name and values.here is demo code array coming like this. 此类在单个数组上运行完美,但是当我添加多维数组不起作用时,我创建了自动获取列名和值的类。这里是演示代码数组。
class myform{
public $key;
public $value;
public $query;
public $con;
public function __construct(){
$this->con = new mysqli('localhost','root','','form')or die('you are losing your mind');}
public function form_values($tablename,$values){
$columns = implode(", ",array_keys($value));
$escaped_values = array_map('esc_sql', array_values($value));
$values = implode("',' ", $escaped_values);
foreach($valuee as $key => $valued){
$this->query = "INSERT INTO {$tablename} ($columns)VALUES('$valued[$key]')";
} return $this->query;
}
}
Here is usage of this code 这是此代码的用法
if(isset($_POST['submitt'])){
$new = new myform;
$values = $_POST;
$query_form = $new->form_values('myguests',$values);
}
Array ( 数组(
[objective] => hj
[full_name] => sdad
[email] => dsafds
[phone] => dasfds
[nationality] => adf

Generally its a bad idea to allow users to build directly your queries to DB. 通常,允许用户直接将您的查询构建到数据库是一个坏主意。
By your case - at the begining of method form_values add code: 根据您的情况-在form_values方法的开头添加代码:
foreach($values as $key => $value) {
if (!is_string($value)) {
//do some stuff. Remove element from array, or convert it to string
}
}
Yahoo... I Got it myself here is the solution hope someone would help. Yahoo ...我自己搞定了,这是希望有人提供帮助的解决方案。
class myform{
public $key;
public $value;
public $query;
public $con;
public function __construct(){
$this->con = new mysqli('localhost','root','','data') or die('you are losing your mind');
}
public function array_implode( $array) {
if ( ! is_array( $array ) ) return $array;
$string = array();
foreach ( $array as $key => $val ) {
if ( is_array( $val ) )
$val = implode( ',', $val );
$string[] = "{$val}";
}
return $string;
}
public function form_values($tablename,$values){
// unset($values['sections']);
$array = $values;
echo '<pre>';
var_export($dg);
echo '</pre>';
$columns = implode(", ",array_keys($values));
$escaped_values = array_map('esc_sql', array_values($dg));
$values = implode("',' ", $escaped_values);
$this->query = "INSERT INTO {$tablename} ($columns)VALUES($values)";
return $this->query;
}
public function insert_form($query_form){
$stmt = $con->prepare($query_form) or trigger_error("ponka");
$stmt->execute();
}
}
Usage 用法
$new = new myform;
$values = $_POST;
$final_values = $new->array_implode($values);
$query_form = $new->form_values('wp_cv',$final_values);
$new->insert_form($query_form);
