Wordpress $ wpdb.插入多个记录

Question

是否有任何方法可以使用$wpdb->insert或在Wordpress中完成以下操作

$wpdb->query($wpdb->prepare)):

INSERT into TABLE (column1, column2, column3) 
VALUES
('value1', 'value2', 'value3'),
('otherval1', 'otherval2', 'otherval3'),
('anotherval1', 'anotherval2', 'anotherval3')

...等等

Answer 1

好的,我明白了!

为实际值和占位符设置数组

$values = array();
$place_holders = array();

初始查询:

$query = "INSERT INTO orders (order_id, product_id, quantity) VALUES ";

然后遍历您要添加的值,并将它们插入适当的数组中:

foreach($_POST as $key => $value)
{
     array_push($values, $value, $order_id);
     $place_holders[] = "('%d', '%d')" /* In my case, i know they will always be integers */
}

然后将这些位添加到初始查询中:

$query .= implode(', ', $place_holders);
$wpdb->query( $wpdb->prepare("$query ", $values));

Answer 2

您也可以使用这种方式构建查询:

$values = array();

// We're preparing each DB item on it's own. Makes the code cleaner.
foreach ( $items as $key => $value ) {
    $values[] = $wpdb->prepare( "(%d,%d)", $key, $value );
}

$query = "INSERT INTO orders (order_id, product_id, quantity) VALUES ";
$query .= implode( ",\n", $values );

我遇到过这个问题,并决定通过使用已接受的答案来构建一个更加改进的功能:

/**
 * A method for inserting multiple rows into the specified table
 * 
 *  Usage Example: 
 *
 *  $insert_arrays = array();
 *  foreach($assets as $asset) {
 *
 *  $insert_arrays[] = array(
 *  'type' => "multiple_row_insert",
 *  'status' => 1,
 *  'name'=>$asset,
 *  'added_date' => current_time( 'mysql' ),
 *  'last_update' => current_time( 'mysql' ));
 *
 *  }
 *
 *  wp_insert_rows($insert_arrays);
 *
 *
 * @param array $row_arrays
 * @param string $wp_table_name
 * @return false|int

function wp_insert_rows($row_arrays = array(), $wp_table_name) {
    global $wpdb;
    $wp_table_name = esc_sql($wp_table_name);
    // Setup arrays for Actual Values, and Placeholders
    $values = array();
    $place_holders = array();
    $query = "";
    $query_columns = "";

    $query .= "INSERT INTO {$wp_table_name} (";

            foreach($row_arrays as $count => $row_array)
            {

                foreach($row_array as $key => $value) {

                    if($count == 0) {
                        if($query_columns) {
                        $query_columns .= ",".$key."";
                        } else {
                        $query_columns .= "".$key."";
                        }
                    }

                    $values[] =  $value;

                    if(is_numeric($value)) {
                        if(isset($place_holders[$count])) {
                        $place_holders[$count] .= ", '%d'";
                        } else {
                        $place_holders[$count] .= "( '%d'";
                        }
                    } else {
                        if(isset($place_holders[$count])) {
                        $place_holders[$count] .= ", '%s'";
                        } else {
                        $place_holders[$count] .= "( '%s'";
                        }
                    }
                }
                        // mind closing the GAP
                        $place_holders[$count] .= ")";
            }

    $query .= " $query_columns ) VALUES ";

    $query .= implode(', ', $place_holders);

    if($wpdb->query($wpdb->prepare($query, $values))){
        return true;
    } else {
        return false;
    }

}
