Fatal error: Call to undefined function error() in /home/chris/public_html/marketplace/add_part.processor.php on line 55

是我的代码。

<?php

它是图像的巨大上传脚本，并将它们插入数据库。我的所有文件字段都有正确的名称，分配为 name =“file []”，我不确定为什么它不起作用。

找不到error（）函数，因此请链接功能控制器或纠正错误功能，这样可以解决您的问题。

public funtion error($data1, $data2)
{
echo "there was a error\n";

var_dump($data1);

echo "<br />";

var_dump($data2);

}
