php上传图片得到路径给表单字段赋值的通用方法
1. 调用方法例子:
大图路径：<input type="text" name="bigImageURL" id="bigImageURL" value="">
<iframe src="uppic.php?id=bigImageURL" width="600" height="25" frameborder="0" scrolling="no"></iframe>
小图路径：
<input type="text" name="smallImageURL" id="smallImageURL" value="">
<iframe src="uppic.php?id=smallImageURL" width="600" height="25" frameborder="0" scrolling="no"></iframe>
2. uppic.php
<?php
header("Content-Type:text/html;charset=GB2312");
?>

注意: 不同的文本框 需要定义id, iframe url : uppic.php?id=文本框id
