在已完成的注册表单上插入图像

Question

我使用PHP / MySQL创建目录注册系统，允许用户插入图像/头像。用户可以注册，一切都进入数据库，我的问题是图像上传和检索。

signup.php

<table border="0" cellspacing="0" cellpadding="4">

    标志：

<td><div class="sm-textfeild-in">
  <div class="textfeild-in">
    <input type="file" name="fileToUpload" id="fileToUpload"  class="validate[required,ajax[ajaxUserCallPhp]]] textfeild-in-152"/>
  </div></div></td>
    <td align="left">
           </td>
    <td>Accepted Formats: <font color="red">jpg, jpeg, png, gif</font></div></td>
</tr>

Save.php

Function.php

 function getdirector()
{
    global $db;
    $sql = "SELECT user_id, profileName, firstname, surname FROM ".PREFIX."users Where admin_approve = '1' and email_verified='1' order by date_register desc limit 3";

    $data = $db->select($sql);
    $return = '';
    $return .= '<table width="340" border="0" cellpadding="2" cellspacing="2">';
    foreach($data as $d)
    {
    $return .= '<tr height="50">
                <td width="80" valign="top">
                    <img src="'.getUserImage($d['user_id'], 75).'" width="76" height="52" class="yash" />

Directory.php

<?php echo getdirectory(); ?>

我可以拉一切，我正在努力获取上传的图像
