Hi people,
i have something really weird going on.
i have a html from that posts to a php-file
in the php i have the following:
if($_POST['name'] !== "") {
// some echoing and mysql connecting code
}
at home everything works perfectly, but the stupid thing is
that at my work, the if-statement ALWAYS executes, wether i post a name or not...
when i change it into
if($_POST['name'] != "") {
// some echoing and mysql connecting code
}
the if~ NEVER executes at my work...
both at home as at my work i use phpdev423, so PHP 4.2.3
at my home i have normal Windows XP running,
at my work Windows 2000 with multiple user accounts
anybody can tell me what is causing this problem?
thanks for all help,
Klaas

or is_string() in this case..
that checks to see if it's a string and to see if it's not an empty string.
Code: Select all
if (is_string(....) && !empty(....))

Actually, is_string() will always evalulate to true on post elements, since all the data are string. Secondly, if the data is missing from the post, is_string() will throw an error, therefore the empty() call should always be first. In this case, only calling empty() is fine.markg85 wrote:or is_string() in this case..

I tend to use is_scalar() instead of is_string(). All scalar values are automatically typecasted into strings when used as a string.markg85 wrote:or is_string() in this case..
