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:

2. uppic.php

<&#63;php
header("Content-Type:text/html;charset=GB2312");

<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>";
 }
}
