Delete Image

[behzad]

Hi There Everyone. I need some help if someone be kind.

 

I have a folder on the server which contains images. I like to delete the images which only thier name start with "wc_106" the file name might look like ( wc_106_xxxxxx.jpg , wc_106_yyyyy.jpg , wv_dddd.jpg ), but I only want to delete the ones having a prefix "wc_106". Could some one help me please?

Use regex, my friend. And then loop through your files and delete the ones that match the regular expression.

friend.. do worry.. every problme has its solution.. but it does not mean.. this is the absolute solution for your problem........

 

 

first: try to read the directory with php function.. using this codes:

 

  $mydir = dir('uploaded_documents/required_doc_file_listing/SF-07112007024747-RAG-01122007193937-0000006');

 

$mydir > is the directory of your image files..

 

then...

 

  while(($file = $mydir->read()) !== false) {

      echo "Filename: $file<BR>";

  }

>> which loops.. until all files from directory return to false...

 

and try to read the $file: which this is filename of loop files....

 

 

then try to read $file using substr();

 

..

$sub_string = substr($file,5); // returns wc_106

 

if($sub_string=='wc_106')

unlink($file);

 

 

this is the complete code:

 

  $mydir = dir('uploaded_documents/required_doc_file_listing/SF-07112007024747-RAG-01122007193937-0000006');

 

  while(($file = $mydir->read()) !== false)

    {

      $sub_string = substr($file,5); // returns wc_106

 

      if($sub_string=='wc_106')

      unlink($file);

 

 

    }

Thanks for that, I am going to go over it and again thanks so much mate.

[cyber_ghost]

no problem.... and your welcome always...

Thanks Mate

 

at start it did not work, I put a zero "0" and a comma in "  $sub_string = substr($file,0,5); // returns wc_106 "

and it is picking the ones up that has "wc_106"

 

 

  $mydir = dir('uploaded_documents/required_doc_file_listing/SF-07112007024747-RAG-01122007193937-0000006');

 

  while(($file = $mydir->read()) !== false)

    {

      $sub_string = substr($file,0,5); // returns wc_106

 

      if($sub_string=='wc_106')

      unlink($file);

 

 

    }

 

================================================

 

Now I am going to make the length of the designated charector to a variable and also the file name prefix

 

$prefix = $_GET['swcl_catcode'];

$length = strlen($prefix);

$mydir = dir('../workout_images');

while(($file = $mydir->read()) !== false)

{

$sub_string = substr($file,0,"$length");

 

if($sub_string =="$prefix")

unlink($file);

}

 

=================================================

 

The only thing is as usual the relative directory problem, I put like  dir ('../wc') it did not work, I had to put it in the same directory as the image files. Well it is working now like this.

 

Again thank you very much for the big help.
