下表和函数属于PHP MySQL数据库集成(https://github.com/blueimp/jQuery-File-Upload/wiki/PHP-MySQL-database-integration)。该函数显示名为“files”的表的所有字段。我想用usr字段扩展表,因为之后,我想只显示与我之前将通过变量传递的用户匹配的行。我的步骤(测试)我用usr字段扩展表,然后进入('admin')usr,并尝试使用这段代码:
$this->options['db_table'].'` WHERE `usr`=admin';
但是什么都不显示......。任何想法?
扩展表(决赛桌):
CREATE TABLE `files` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`usr` varchar(255) DEFAULT NULL
`name` varchar(255) DEFAULT NULL,
`size` int(11) DEFAULT NULL,
`type` varchar(255) DEFAULT NULL,
`url` varchar(255) DEFAULT NULL,
`title` varchar(255) DEFAULT NULL,
`description` text,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
PHP函数:
<?php
$options = array(
'delete_type' => 'POST',
'db_host' => 'localhost',
'db_user' => 'root',
'db_pass' => '',
'db_name' => 'example',
'db_table' => 'files'
);
….
protected function set_additional_file_properties($file) {
parent::set_additional_file_properties($file);
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
$sql = 'SELECT `id`, `type`, `title`, `description` FROM `'
.$this->options['db_table'].'` WHERE `name`=?';
$query = $this->db->prepare($sql);
$query->bind_param('s', $file->name);
$query->execute();
$query->bind_result(
$id,
$type,
$title,
$description
);
while ($query->fetch()) {
$file->id = $id;
$file->type = $type;
$file->title = $title;
$file->description = $description;
}
}
