I have a text input:
<label for="pt"><b style="color:white"> Company name </b></label>
<input type="text" name="company" maxlength="100" required>
And I want to insert into a psql database:
$comp= $_POST["company"];
$comptr = trim($comp);
When I have inserted it nothing happened. The data in the table remained the same with multiple whitespaces
here is the insert:
$queryres = "insert into company (v1, v2, ...) VALUES ('$comptr ','$v2', ...)";
$resultsel = pg_query($con, $queryres);
Example:
I wrote this in the input:
" TEST COMP. "
in the table stayed this:
" TEST COMP. "
and I want to change to this:
"TEST COMP."
You can delete multiple whitespaces within a text not with trim()
but quite well with preg_replace()
. Make a combination of trim()
and preg_replace()
.
$comp = $_POST["company"];
echo trim(preg_replace('/\s+/', ' ', $comp));
// putput: TEST COMP.
