CheckFile

string
CFile::CheckFile(
 array file,
 int max_size = 0,
 string mime_types = false,
 string Ext = false,
 bool ForceMD5=false,
 bool SkipExt=false
)

The method verifies the size, extension and mime type of the file. In case of an error, the method returns a string containing the error description. Static method.

Parameters

Parameter	Description	Available from version
file	Array with the file data of the following format: Array( "name" => "file name", "size" => "size", "tmp_name" => "temporary path to file on the server", "type" => "type of loaded file", "del" => "flag - specifies if an existing file is to be deleted from the database (Y\|N)", "MODULE_ID" => "module name") This array can be obtained, for example, by joining arrays $_FILES[field_name] and Array("del" => ${"field_name"."_del"}, "MODULE_ID" = "module_name").
max_size	Maximum file size (bytes). Optional parameter . By default - "0" - without limits.
mime_types	Allowed mime type of a file (e.g. "image/"). Verification is performed using data received from a user, this is why you should use extensions for safer checks. Optional. The default value is false, which means no restriction applies.
Ext	Comma-separated permitted file extensions. Optional parameter. By default - "false" - without limits. File Extensions must be specified without a period, for example, not as .pdf, but as pdf. To verify the permissible extensions and the current extension of the loaded file, the current extension is retrieved by the CFile::GetFileExtension method, which returns the extension name without a period.
ForceMD5	Optional parameter. By default - "false".
SkipExt	Optional parameter. By default - "false".

Examples of use

<?
$arrFile = array_merge(
    $_FILES["ATTACHED_IMAGE"], 
    array("del" => ${"ATTACHED_IMAGE_del"}, "MODULE_ID" => "forum"));

$res = CFile::CheckFile($arrFile, 200, "image/", CFile::GetImageExtensions());
if (strlen($res)>0) $strError .= $res."<br>";
?>
