Legend of Sword and Fairy 5 prequel branch TP framework multi-upload domain upload pictures

Question:

When learning to use the TP framework to build an e-commerce website, when adding a product form, you need to upload product logos and product image pics. There are two upload domains. The first upload domain is the logo. Only one upload is uploaded, and the second one is uploaded. The domain is pics, upload multiple pictures. When using the following code, an error is always reported: Illegal file upload!

<span>$upload</span> =<span> \Think\Upload;
</span><span>$info</span>=<span>$upload</span>->upload();

Solution:

When there are multiple upload domains, you should use the upload method as follows to specify the upload domain to be processed:

$upload = \Think\Upload;
$info1 = $upload->upload(array('logo'=>$_FILES['logo']);
$info2 = $upload->upload(array('pics'=>$_FILES['pics']);

Reference:

Title:

T P framework will report an error of "illegal upload" when uploading pictures

Content:

TP framework will report an error of "illegal upload" when uploading pictures. Pay attention to the following two points:

1. There are multiple upload domains in $_FILES problem, so different upload domains are named differently;

2. If there are some uploaded images in the same upload domain, the uploaded information must be collected again (collected into a non-empty one-dimensional array);

Specific code As follows;

First case:

<span>if</span>(<span>$this</span>-><span>_hasImg())

The above has introduced the TP framework for multi-upload domain uploading of images in the Legend of Sword and Fairy 5 prequel branch, including the content of the Legend of Sword and Fairy 5 prequel branch. I hope it will be helpful to friends who are interested in PHP tutorials.
