[PHP] Image Uploads beeing corupted
Hey guys,
I got my uploads to work thanks to some peoples help here in this
newsgroup but now im having a problem with the files beeing corrupted
upon upload. not sure why any help would be greatly apreciated.
I have included my code again if it helps any.
<>
function UploadImage(){
global $HTTP_POST_FILES;
global $ImageFile;
reset($HTTP_POST_FILES);
$pic_file = $HTTP_POST_FILES['ImageFile'];
copy ($pic_file['tmp_name'], "../images/$ImageFile_name");
}
<>
I've found that just doing this seems to do the same
function UploadImage(){
global $ImageFile;
copy ($ImageFile, "../images/$ImageFile_name");
}
Thanks
Ryan Stephens

Re: [PHP] Image Uploads beeing corupted
the funny thing is this
the information is beeing inserted into the database... the file is beeing
uploaded (as i can see it in the directory). I can get results from
$ImageFile
$ImageFile_name
$ImageFile_size
but i cant get a result for $ImageFile_type this comes up blank
there is obviously some connection, but just not sure what.

[PHP] Problem Solved
I figured i would post my solution to the problem that i found somewhere. It
had nothing to do with anything i was doing. Its a bug in some versions of
PHP.
here is the function i had to use to fix this
function fix_php_upload_bug($tmp){
$infile=fopen($tmp,"r"); // Open the file for the copy
$outfile=fopen("$tmp.new","w"); // create a new temp file
$header=fgets($infile,255); //get the 1st line (netscape sometimes doesn't
add a Content-type line)
//if its more than just a \r\n sequence then
if (strlen($header)>2) $header=fgets($infile,255); //get next line also
while(!feof($infile)) { // Loop through the remaining file
$temp=fread($infile,128);
fwrite($outfile,$temp,strlen($temp)); //copying contents to new temp file
}
fclose($outfile);
fclose($infile);
copy("$tmp.new","$tmp"); //replace the original with our new bug fixed file
unlink("$tmp.new"); //and delete the new file
return $tmp;
}

[PHP] CheckBoxes and Arrays
Im trying to output a list of options, each with a checkbox named "ChkBox" and with a value of the ID number from the database. This is no prob. The thing is, i want to be able to select some of those checkboxes (any number, in combination) and delete the information from the database that is associated with the ID for that CheckBox. Example of input tag: <--> echo "ID\">\n"; <---> Now i thought that if i selected say items 1, 2, 3 from the list (and there IDs are 1, 2, 3) then When i submit the form a comma delimited string would be created (an array even not sure what it is). How would i loop through this list and break it apart so i can delete each record from the database that was selected.
