Question

I have searched a lot and tried javascript replace() function and str_replace,addslashes , strip slashes as well but i am not getting the right output.

This is what im doing:

str_replace("\\","\\\\", "C:wamp\www\desi\uploads\artist\bg\9.jpg";

THe output i am getting is:

C:wampwwwÞsiuploads\A rtist\B g .jpg

Then another way i tried:

var clean=  "<?php echo str_replace("\\","@",LINKCONSTANT); ?>".replace("@","\\");

Still not working any idea ?

Answer 1

the problem isn’t solvable by using str_replace like that because the string in double quotes will have the slashes processed by PHP as escape sequences. Using str_replace like this isn’t going to solve the problem of PHP (or javascript) handling string escapes – once you have got a backslash into a string it will stay there quite faithfully.

However string constants will work in single quotes as follows:

'C:wamp\www\desi\uploads\artist\bg\9.jpg'

but as pointed out elsewhere the directory separator in windows is internally handled as either “/” or “\” so just use the “/” (for api calls) and you’ll be fine.

If you wish to output a string that is safe to be parsed by javascript then do:

echo "var str = ".json_encode('C:wamp\www\desi\uploads\artist\bg\9.jpg').";";

which will output in a javascript compatible way:

var str = "C:wamp\\www\\desi\\uploads\\artist\\bg\\9.jpg";
