如何在 ci4 应用程序中准确指定要上传的图像的大小。我想上传 49.7kb 的图像,但由于大小限制而无法上传。 如何将大小设置为最大 5mb?目前我想我将其设置为 5mb 我的形象规则是:
$profile_pix_validation_rule = [
'userfile' => [
'label' => 'Image File',
'errors' => ['max_size' => "Image size can be 10mb max"],
'rules' => [
'uploaded[passport_image]',
'mime_in[passport_image,image/jpg,image/jpeg,image/png]',
'max_size[profile_pix,5120]',
'max_dims[profile_pix,1024,768]',
],
],
];
也许这是因为您的字段名称不同。
$profile_pix_validation_rule = [
'passport_image' => [ // The correct field name
'label' => 'Image File',
'rules' => [
'uploaded[passport_image]', // The field name here should match the input name
'mime_in[passport_image,image/jpg,image/jpeg,image/png]', // Allowed mime types
'max_size[passport_image,5120]',
'max_dims[passport_image,1024,768]',
],
'errors' => [
'max_size' => 'Image size can be 5 MB max',
'uploaded' => 'Please upload an image file.',
'mime_in' => 'Only JPG, JPEG, and PNG files are allowed.',
'max_dims' => 'Image dimensions should not exceed 1024x768 pixels.',
]
],
];
此外,表单应使用
enctype="multipart/form-data"
创建
表单示例(基本html)
<form method="post" enctype="multipart/form-data">
<input type="file" name="passport_image">
<input type="submit" value="Upload">
</form>
并且在
php.ini
upload_max_filesize = 5M
post_max_size = 8M
max_execution_time = 300
max_input_time = 300
