About PHP upload and processing of multi-image, Trouble master to write a piece of code for learning
The requirements are as follows:
There are 4 pictures under a product name. The image is uploaded to the "upimg" folder in the current path, and the picture path is stored in the MySQL corresponding field.
So when I do product information filling in, for the same product name, you must upload 4 images.

---------Database structure:
Database name: atest,
Table name: Prodcut,
Table corresponding to the field: Pname,pic1,pic2,pic3,pic4 ... (All char types)

--------HTML Form I designed this:

HTML Code

A few things to note:
1, in the database, a product name + four image path to form a piece of data, rather than save as multiple data.
2, the image file must be renamed, or there will be duplicates;
3, before uploading the file to detect whether the image format is jpg,bmp,gif or PNG, otherwise do not upload;
4, the volume of the uploaded image can not exceed 2M; that is: Name= "max_file_size" value= "2000000"

Single image upload class: uploadclass.php (corresponding to multi-image upload, rename it, and the code snippet in the corresponding changes, can be multiple references, multiple uploads)

PHP Code

  Return and try Again?click me "; exit;} else{$filename =explode (".", $_files[' pic ' [' name ']);//Ibid., Pic needs to be renamed do{$filename [0]=random (10);//When using the function random, The same should correspond to renaming $name=implode (".", $filename);//$name 1= $name. " MCNCC "; $uploadfile = $uploaddir. $name;//This $uploadfile is the picture path you want to insert into the database corresponding fields, need to change}while (file_exists ($uploadfile)) ///The function name needs to correspond to the most changed if (Move_uploaded_file ($_files[' pic '] [' tmp_name '], $uploadfile))//pic need to correspond to the most changed {if (Is_uploaded_file ($_ files[' pic ' [' tmp_name ']))//pic need to correspond to make changes {echo "the Images Upload failed!";} Else{echo "
  
   
    Your file has been uploaded:
   
  

  
   
  "//src=" is the most changed echo.

  
   
    Continue to upload
