Code: Select all: //jika sks sama dengan atau lebih kecil dari 24 if($i =< 24){ echo '<input type="checkbox" />' } //jika sudah 24 akan dikosongkan else {echo '<input type="checkbox" disable="disabled" />';}

sperti ini ga yg om maksud?

Begini, pertama, beri attribut class di checkbox nya:

Code: Select all: //Pada contoh saya beri attribut class "chk_sks" echo "<td id=k4$i><input type=checkbox name=mk[] onclick=hitungtotal() value=".$kode[$i]." id=mk".$i." class='chk_sks'></tr>";

Di script Javascript-nya tambahkan fungsi ini:

Code: Select all: var allHTMLTags = new Array(); function disabledElementByClass(theClass) { var allHTMLTags=document.getElementsByTagName("*"); for (i=0; i<allHTMLTags.length; i++) { if (allHTMLTags[i].className==theClass) { allHTMLTags[i].disabled=true; } } }

Cara manggil fungsinya begini:

Code: Select all: if (jum >= 30){ disabledElementByClass("chk_sks"); }
