The example in this article describes how to obtain the path for uploading images in PHP and assign values ​​to form fields. Share it with everyone for your reference, as follows:

1. Example of calling method:

Large image path:

<input type="text" name="bigImageURL" value="">
<iframe src="uppic.php&#63;id=bigImageURL" width="600" height="25" frameborder="0" scrolling="no"></iframe>

Small image path:

<input type="text" name="smallImageURL" value="">
<iframe src="uppic.php&#63;id=smallImageURL" width="600" height="25" frameborder="0" scrolling="no"></iframe>

2. uppic.php

<&#63;php
header("Content-Type:text/html;charset=GB2312");
&#63;>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<HTML xmlns="http://www.w3.org/1999/xhtml">
<HEAD>
<TITLE>图片上传</TITLE>
<META http-equiv=Content-Type c name=GENERATOR>
<style type="text/css">
<!--
input{border-width:1px;border:1px solid #bdbcbd;padding:3px 0 3px 5px;}

</style>
</HEAD>
<BODY leftmargin=0 topmargin=0>
<&#63;php
$id=$_GET["id"];
//echo "id==".$id;
switch($_GET["action"])
{
case "up":
 upmovie($id);
 break;
default:
 upinput($id);
 break;
}
function upinput($id){
&#63;>
<SCRIPT language=javascript>
function check() 
{
 var strFileName=document.form.strPhoto.value;
 if (strFileName=="")
 {
   alert("请选择要上传的文件");
 document.form.strPhoto.focus();
   return false;
  }
 return true;
}
</SCRIPT>
<form action="uppic.php&#63;action=up&id=<&#63;=$id&#63;>" enctype="multipart/form-data" name="form" method="post"  type="file" size="40">
<input type="submit" name="Submit" value="上 传" class=inputbut />
</form>
</BODY>
<&#63;php
}
function upmovie($id){
 global $web_picdir;
 $savePath=dirname(__FILE__)."/".$web_picdir;
 $str = date('YmdHis');
 if($_FILES['strPhoto']['name']!='')
 {
  $tmp_file=$_FILES['strPhoto']['tmp_name'];
  $file_types=explode(".",$_FILES['strPhoto']['name']);
  $file_type=$file_types[count($file_types)-1];
  if(strtolower($file_type)!="jpg"&strtolower($file_type)!="gif"&strtolower($file_type)!="bmp"&strtolower($file_type)!="png"){
   echo "<span style=/"color:red;line-height: 25px;/">格式错误请重新上传<a href=# /a></span>";
   exit;
  }
  $file_name=$str.".".$file_type;
  if(!copy($tmp_file,$savePath.$file_name)){
  echo "<span style=/"color:red;line-height: 25px;/">上传错误请重试!!<a href=# /a></span>";
  }else{
  //echo "<span style=/"olor:red;line-height: 25px;/">上传成功</span><script>parent.document.getElementById(/"bigImageURL/").value=/"".$file_name."/"</script>";
  echo "<span style=/"olor:red;line-height: 25px;/">上传成功</span><script>parent.document.getElementById(/"{$id}/").value=/"".$file_name."/"</script>";
  echo "<a href=# /a>";
  }
 }else{
 echo "<span style=/"color:red;line-height: 25px;/">请选择需要上传的文件<a href=# /a></span>";
 }
}
?>

Note: Different text boxes need to define ids, iframe url: uppic.php?id=text box id
