I am making a form that allows a user to create a page that has a qr code to link it to the page. I am only having one problem, I cant get the picture to upload to the database and display after the form has been submitted. it displays the file name of the photo just not the photo.

here is my form code

<?php
ob_start();
session_start();


<html>
<head>


</head>

<title>create </title>
<center> <font size="+5"> Create </center>
<body background="">
<p



<table align="center" cellpadding="0" border="0" cellspacing="1">
<form name="createTeaOffer" action="submit.php" method="get">

<tr> <td> <font size="+3"> Headline:</td> <td> <input type="text" name="hea"> </td> </tr>
<br />
<tr> <td> <font size="+3"> Photo:  </td> <td> <input type="file" name="pho"> </td> </tr>
<br /> 
<tr> <td><font size="+3">Description: </td> <td><input name="des" type="textarea"> </td>   </tr>
<br />
<tr> <td><font size="+3">Contact Method: </td> <td> <input name="con" type="radio" value="email" name="email" >Email <input type="radio" value="phone"   method="get" name="phone"> Phone </td> </tr>
<br />
<tr> <td><font size="+3">Email or Phone: </td> <td> <input name="ema" type="text"> </td> </tr>
<br />
<tr> <td><font size="+3">Location: </td> <td> <input name="loc" type="text"> </td> </tr>
<br />
<tr> <td><font size="+3">Expiration (yyyy-mm-dd): </td> <td> <input name="exp" type="date"> </td> </tr>
<br />
<tr> <td><font size="+3">Distance: </td> <td> <input name="dis" type="text"> </td></tr>
<br />
</font></table>
<input type="submit"> 
</form>
</body>
</html>

and here is my submit code

<?php
ob_start();
session_start();
$template = <<<EOD

这是一个普遍的答案，我无法真正解释实际代码，但您不能将图像上传到“数据库”，因为数据库（通常）是基于文本的，除非您使用图像编码。如果您的意思是上传到您网站的文件系统，请参阅本教程http://www.w3schools.com/php/php_file_upload.asp并将图像 URL 添加到您的数据库。然后，您可以使用<?php echo '<img src="' . $imageURL . '">' ?>在用户个人资料上回显图像。

也像 dagon 说的那样，你的 html 有一些问题，例如你把标题放在正文部分，而它应该放在标题部分。我还建议使用 $_POST 请求，而不是 $_GET 请求，因为它更安全。更好地了解 html 的基础知识，有大量可用资源。字体标签的使用会让普通的 Web 开发人员痛苦地哭泣，因为它甚至不应该再使用了。学习 CSS，伙计（放在<style>td { font-size:15px }</style>head 部分）。

最后，调用表单字段名称，如“loc”和“con”是命名字段的糟糕方式。如果你是唯一一个编写代码的人，那你为什么要把名字弄得如此混乱呢？
