PHP/MySQL：空白图像路径

我有一个难题，我正在尝试从上传/使用的路径检索图像 . 它显示空白图像，但如果我放置原始路径，它显示良好

我试图根据发送方和接收方实际匹配存储信息的两个参数进行选择

 $mergeyou = $flash->query("SELECT * FROM `user` WHERE `username` IN
       (
       SELECT `sender`
       FROM `merge`
       WHERE `reciever`='{$prof['username']}')");
       $uwonm = $flash->query("SELECT * FROM `merge` WHERE `reciever`='{$prof['username']}' AND `sender`='{$_POST['sender']}'"); //this is the code for selecting image path from the database table named "merge"
       $muproff = $uwonm->fetch();
       if($mergeyou->rowCount() > 0){
    //Update Paid
    if(isset($_POST['conpay'])){
        $paydon = date('d-M-Y');
        $flash->query("INSERT INTO `donation` (sender,reciever,amount,payedon,status)
        VALUES('{$_POST['sender']}','{$muproff['reciever']}','{$emoney}','{$paydon}','1')");
        $mergsens = date('dmYhi');
        $flash->query("DELETE FROM `merge` WHERE `reciever`='{$prof['username']}' AND `sender`='{$_POST['sender']}'");
        $seemer = $flash->query("SELECT * FROM `merge` WHERE `reciever`='{$prof['username']}' AND `sender`='{$_POST['sender']}'");
        if($seemer->rowCount() < 1 AND $prof['right'] < 1){
        $flash->query("UPDATE `user` SET `tomerge`='100',mergesince='{$mergsens}' WHERE `username`='{$muproff['reciever']}'");
        }
        $flash->query("UPDATE `user` SET `tomerge`='1',mergesince='{$mergsens}' WHERE `username`='{$_POST['sender']}'");
        $updref = $flash->query("SELECT * FROM `user` WHERE `username` IN

你为什么要用条纹标签？使用php的错误报告检查错误，并使用mysqli_error$flash查看是否有任何返回。检查你的路径，运行一个var_转储，看看你的html source.OMG，这段代码。使用mysqli/pdo使用准备好的语句，您是否注意到代码和描述之间的任何差异？提示：计算您在路径中使用上载的次数
