laravel Validate Request-CodePudding

For Examle I have Request Validation

'images.*'            => 'mimes:jpg,jpeg|max:10240',
'images'              => 'max:5',

It work In Create But , in update how I can check It , for example I already uploaded 4 image And In update I must add Only One Image , How I can validate it , is there any idea

CodePudding user response：

How about setting the validation value dynamically? Like, fetch the image record count first then set the value for the image validation.

//Fetch the remaining count
$remaining_image_count = 3;
$image_count_validation = 'max:' . $remaining_image_count;

//Setting the validation value
'images.*'            => 'mimes:jpg,jpeg|max:10240',
'images'              => $image_count_validation,

CodePudding user response：

if i understood your question right you want to check if theres maximum of 5 in the Database.

 $count = 5 -  Media::where('post_id', $post->id)->count();
    $request->validate([
        'title' => 'required|min:20',
        'description' => 'required|min:50',
        'img' => 'array|max:'.$count,
        'img.*' => 'image|mimes:jpg,jpeg,png'
    ]);

if that was your question. Please be more Specific
