我正在尝试在wordpress中创建一个自定义插件，在其中我创建一个表并使用插件插入数据。表创建成功 但数据未插入到表中。 这是我的代码
global $jal_db_version;
$jal_db_version = "1.0";
function jal_install() {
global $wpdb;
global $jal_db_version;
$table_name = $wpdb->prefix . "demo1";
$sql = "CREATE TABLE IF NOT EXISTS $table_name (
id int(9) NOT NULL AUTO_INCREMENT,
name varchar(255) NOT NULL,
email varchar(255) NOT NULL,
password varchar(255) NOT NULL,
PRIMARY KEY id (id)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;";
$wpdb->query($sql);
pu_insert_custom_table($table_name);
}
function pu_insert_custom_table($table_name)
{
global $wpdb;
$wpdb->insert(
'$table_name',
array(
'name'=>'abc',
'email'=>'abc@gmail.com',
'password'=>'123456'
),
array(
'%s',
'%s',
'%s'
)
);
}
您需要
将插入查询修改为：
$wpdb->insert(
$table_name,
array(
'name'=>'abc',
'email'=>'abc@gmail.com',
'password'=>'123456'
),
array(
'%s',
'%s',
'%s'
)
);
你可以试一试：
<?php
global $jal_db_version;
$jal_db_version = '1.0';
function jal_install() {
global $wpdb;
global $jal_db_version;
$table_name = $wpdb->prefix . 'liveshoutbox';
$charset_collate = $wpdb->get_charset_collate();
$sql = "CREATE TABLE $table_name (
id mediumint(9) NOT NULL AUTO_INCREMENT,
time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,
name tinytext NOT NULL,
text text NOT NULL,
url varchar(55) DEFAULT '' NOT NULL,
UNIQUE KEY id (id)
) $charset_collate;";
require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
dbDelta( $sql );
add_option( 'jal_db_version', $jal_db_version );
}
function jal_install_data() {
global $wpdb;
$welcome_name = 'Mr. WordPres';
$welcome_text = 'Congratulations, you just completed the installation!';
$table_name = $wpdb->prefix . 'liveshoutbox';
$wpdb->insert(
$table_name,
array(
'time' => current_time( 'mysql' ),
'name' => $welcome_name,
'text' => $welcome_text,
)
);
}
然后用wordpress钩子单独调用这些函数，如下所示：
register_activation_hook( __FILE__, 'jal_install' );
register_activation_hook( __FILE__, 'jal_install_data' );
