irkevin Posted October 1, 2007 Share Posted October 1, 2007 Hi, sorry for bugging you again.. I have a form.. the php code to insert to data in the database works well.. but now, i'm trying to prevent people from being childish with the form.. sorry for the expression.. If i do <?php if(!$_POST['name']){ echo "You did not enter your name"; } ?> basically, it will tell the user that he didn't enter his name.. But i noticed on the net, some form, when you just hit spacebar once and then click submit, it submits the data and obviously, you'll get only a space in the database.. Why is it so? Is there a way to prevent this? If someone know how to prevent this, plz tell me. will be very grateful.. Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 1, 2007 Share Posted October 1, 2007 <?php if(!$_POST['name']||empty($POST['name'])){ echo "error: message";}?> Quote Link to comment Share on other sites More sharing options...
irkevin Posted October 1, 2007 Author Share Posted October 1, 2007 the empty code might do the trick, but wont it take the space as something to put in the database? I heard about striplashes and addslashes etc etc.. what does it do really? P.S: Sorry for my bad english Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 1, 2007 Share Posted October 1, 2007 addslashes adds a slash after something strip slashes removes slashes from something. if you want to remove whitespace you need to use the trim function also empty function if nothing is input into that field it wont allow you to post it errors Quote Link to comment Share on other sites More sharing options...

irkevin Posted October 1, 2007 Author Share Posted October 1, 2007 yes it is entering in the database.. and it's showing a space on the shoutbox too.. basically it shows the space when i hit spacebar and press enter.. but i don't want that to happen even if i hit spacebar and press enter..

irkevin Posted October 1, 2007 Author Share Posted October 1, 2007 [code]my server is a bit slow.. i should wait a few mins.. btw, dont you think i should add this afterwards if(!$shouter || !$shout){ //do nothing }[/code] ?? What you think?? Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 1, 2007 Share Posted October 1, 2007 no try the code now i modified it because you had the variables switched Quote Link to comment Share on other sites More sharing options...
irkevin Posted October 1, 2007 Author Share Posted October 1, 2007 Ok i'll try it once my !@#$%^ server is ok ..lol Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 1, 2007 Share Posted October 1, 2007 lol okay Quote Link to comment Share on other sites More sharing options...
irkevin Posted October 1, 2007 Author Share Posted October 1, 2007 I tried the code you gave me but it didn't work.. then i tried added this part if(!$shouter || !$shout){ //do nothing } I added !$shout, and it works perfectly.. so normally, you're replacing a space with this '', which means nothing.. it's same as leaving a field blank, right?? so it's the same as !$shout i presume.. Am i right? huh.. 0_o.. lol but now when i type a normal text, it goes like this thsiisjustatest Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 1, 2007 Share Posted October 1, 2007 no its not it trims all whitespace from the beggining and end of a string! Quote Link to comment Share on other sites More sharing options...
irkevin Posted October 1, 2007 Author Share Posted October 1, 2007 i tried it with the code you gave me,, but the text goes like this thisisjustatest.. instead of this is just a test ! see what i mean? Quote Link to comment Share on other sites More sharing options...
darkfreaks Posted October 1, 2007 Share Posted October 1, 2007 remove the string replace code. and keep the trim code Quote Link to comment Share on other sites More sharing options...
