jake2891 Posted January 5, 2011 Share Posted January 5, 2011 this is basically what your after needs a few tweaks to put your variable back in etcc and to hide the submit button again if there are no checked boxes. <html> <head> <script type="text/javascript"> function check(){ var graphics = document.getElementsByName("graphic[]"); for(i=0;i<graphics.length;i++){ if(graphics[i].checked){ if(document.getElementById('submit').style.display=='none'){ document.getElementById('submit').style.display='block'; } } } var text = document.getElementsByName("text[]"); for(i=0;i<text.length;i++){ if(text[i].checked){ if(document.getElementById('submit').style.display=='none'){ document.getElementById('submit').style.display='block'; } } } } </script> </head> <form action="#" method="post"> <input type='hidden' name='service_id' value='1'> <table width='1000px' border='0' cellspacing='0'> <tr> <td class='td_header_2' align='left' colspan='2' width='50%'> Available products for service: bla </td> </tr> <tr> <table width='600px' class='tbl_content_box' border='0' cellspacing='0'> <tr> <td width='100px'>Products:</td> <td width='100px'>Graphic</td> <td width='100px'>Text</td> </tr> </table> <table> <table width='600px' class='tbl_content_box' border='0' cellspacing='0'><?php $product_names = array(1=>"one",2=>"two"); foreach($product_names as $k=>$v) { ?> <tr> <td > </td><td width='200px'>bla</td> <td width='200px'><input type="checkbox" name="graphic[]" value="<?=$k?>" onclick="check()"/></td> <td width='200px'><input type="checkbox" name="text[]" value="2" onclick="check()"/></td> </tr> <?php } ?> </table> <table> <tr> <td> <input id="submit" type='submit' name='submit' value='Submit' style="display:none"> <?php if($_POST['graphic']){ $graphics_selected = $_POST['graphic']; foreach($graphics_selected as $val) { echo "bla"; } } ?> </td> </tr> </table> </form> Quote Link to comment Share on other sites More sharing options...

helloise Posted January 5, 2011 Author Share Posted January 5, 2011 thank you thank you!!! its working...now just one last thing: how can i check if graphic[] OR text[] contains nothing, thus array is empty??? also the code: if($_POST['graphic']) { $graphics_selected = $_POST['graphic']; //is line 62 foreach($graphics_selected as $val) { echo $val."\n"; } } give error: Undefined index: graphic in /home/helloises/svn_wappool/apps/lpmanager/modules/doc/templates/productSuccess.php on line 62 thanks very much Quote Link to comment Share on other sites More sharing options...
jake2891 Posted January 5, 2011 Share Posted January 5, 2011 im not sure why your getting the undefined index as i dont have that problem when i run the code. if you want to check on the php side you can use the empty function or javascript use the length function. post ur full code for me to see with regards to that index problem Quote Link to comment Share on other sites More sharing options...
helloise Posted January 5, 2011 Author Share Posted January 5, 2011 the full text is exactly like you gave it to me everything works perfect.. i was thinking maybe i can set a variable(boolean) in the javascript part and check that later in the code???(but dont know how to do that though) just to see if the two arrays contain something..because if one of them contain nothing and i hit submit i get errors on the second form <html> <head> <script type="text/javascript"> function check() { var graphics = document.getElementsByName("graphic[]"); for(i=0;i<graphics.length;i++) { if(graphics[i].checked) { [color=red]var gchecked = true;[/color] if(document.getElementById('submit').style.display=='none') { document.getElementById('submit').style.display='block'; } } } var text = document.getElementsByName("text[]"); for(i=0;i<text.length;i++) { if(text[i].checked) { [color=red]var tchecked = true;[/color] if(document.getElementById('submit').style.display=='none') { document.getElementById('submit').style.display='block'; } } } } </script> </head> <form action="<?php echo url_for('doc/document'); ?>" method="post"> <input type='hidden' name='service_id' value='<?php echo $service->getId() ?>'> <table width='1000px' border='0' cellspacing='0'> <tr> <td class='td_header_2' align='left' colspan='2' width='50%'> Available products for service: <?php echo $service->getName()?> </td> </tr> <tr> <table width='600px' class='tbl_content_box' border='0' cellspacing='0'> <tr> <td width='100px'>Products:</td> <td width='100px'>Graphic</td> <td width='100px'>Text</td> </tr> </table> <table width='600px' class='tbl_content_box' border='0' cellspacing='0'><?php $product_names = LpmPagePeer::getByAllProdNames($service->getId()); foreach($product_names as $product_row) { ?> <tr> <td > </td><td width='200px'><?php echo $product_row->getName();?></td> <td width='200px'><input type="checkbox" name="graphic[]" value="<?php echo $product_row->getId();?>" onclick="check()"/></td> <td width='200px'><input type="checkbox" name="text[]" value="<?php echo $product_row->getId();?>" onclick="check()"/></td> </tr> <?php } ?> </table> <table> <tr> <td> <input id="submit" type='submit' name='submit' value='Submit' style="display:none"> <?php [color=red] ///if isgchecked or istchecked is false then i must display a warning[/color] ?> </td> </tr> </table> </form> thanks for all your help so far..just this one last hurdle Quote Link to comment Share on other sites More sharing options...
jake2891 Posted January 5, 2011 Share Posted January 5, 2011 hmm well if you make it that when there is no checked boxes the submit dissappears again like i mentioned earlier you wont get an empty array on the next page unless you get a sneaky hacker then you would have to validate alot more.

jake2891 Posted January 5, 2011 Share Posted January 5, 2011 change the javascript function check i gave you to this instead its overkill but it will work. function check(){ var none_checked = false; var graphics = document.getElementsByName("graphic[]"); var text = document.getElementsByName("text[]"); for(i=0;i<graphics.length;i++){ if(!graphics[i].checked){ none_checked = true; } } for(i=0;i<text.length;i++){ if(!text[i].checked){ none_checked = true; } } if(none_checked == true){ document.getElementById('submit').style.display='none'; }else{ document.getElementById('submit').style.display='block'; } for(i=0;i<graphics.length;i++){ if(graphics[i].checked){ if(document.getElementById('submit').style.display=='none'){ document.getElementById('submit').style.display='block'; } } } for(i=0;i<text.length;i++){ if(text[i].checked){ if(document.getElementById('submit').style.display=='none'){ document.getElementById('submit').style.display='block'; } } } } Quote Link to comment Share on other sites More sharing options...
jake2891 Posted January 5, 2011 Share Posted January 5, 2011 just do this on the next form <?php if($_POST['text']){ echo 'got text'; }else{ echo 'no text'; } if($_POST['graphic']){ echo 'got graphic'; // can do something now }else{ echo 'no graphic'; // cant do shit } ?> Quote Link to comment Share on other sites More sharing options...
