note 29581 added to function.urlencode

When you're filling in a form sometimes you might forget some of the required fields and when you go back everything is empty and you have to fill in all of the fields again. To avoid this you can pass the values of the filled fields to the same page. But some of the values of the variables can contain spaces, names for example:'John Smith'. So i use str_replace() instead of urlencode() to replace spaces with '+' and 'John Smith' turns into 'John+Smith'. Here is the example: <?php function get_rid_of_spaces_and_empty_values($name, $city, $mail, $phone) { $href_link = "your_form.php"; if ($name) { $name = str_replace(" ", "+", $name); $href_link .= "?name=$name"; } if ($city) { $city = str_replace(" ", "+", $city); $href_link .= $href_link == "your_form.php" ? "?city=$city" : "&city=$city"; } if ($mail) { $mail = str_replace(" ", "+", $mail); $href_link .= $href_link == "your_form.php" ? "?mail=$mail" : "&mail=$mail"; } if ($phone) { $phone = str_replace(" ", "+", $phone); $href_link .= $href_link == "your_form.php" ? "?phone=$phone" : "&phone=$phone"; } return $href_link; } /*If there is no value for $name and $city == city_value, $href_link will be "your_form.php?city=city_value"; else it will be "your_form.php?name=name_value&city=city_value" etc.*/ function check_all_inputs_in_the_form($name, $city, $mail, $phone) { $href_link = get_rid_of_spaces_and_empty_values($name, $city, $mail, $phone); if ( (!$name)||(!$city)||(!$mail)||(!$phone) ) { print(" <html><head><title>form</title></head>\n ". " <body>Please, go <a href=\"$href_link\">back</a> and fill in all required fields.\n ". " </body></html>\n " ); exit; } } if (!$hid) { ?> <html><head><title>form</title></head> <body><form name="something" method="post" action="your_form.php"> name:<input type="text" name="name" <?php if ($name) print( "value=\"$name\"" ); ?>> e-mail:<input type="text" name="mail" <?php if ($mail) print( "value=\"$mail\"" ); ?>> phone:<input type="text" name="phone" <?php if ($phone) print( "value=\"$phone\"" ); ?>> city:<input type="text" name="city" <?php if ($city) print( "value=\"$city\"" ); ?>> <input type="hidden" name="hid" value="hid"> <input type="submit" value="submit" name="submit"></form></body></html> <?php } if ($hid == "hid") check_all_inputs_in_the_form($name, $city, $mail, $phone); ?> I hope this will be helpful :) -- http://www.php.net/manual/en/function.urlencode.php http://master.php.net/manage/user-notes.php?action=edit+29581 http://master.php.net/manage/user-notes.php?action=delete+29581 http://master.php.net/manage/user-notes.php?action=reject+29581
