    copied!<p>Ok, I am pretty stumped, looking in this code for more than 3 hours.</p> <p>I generate array of check boxes, like this:</p> <pre><code>&lt;?php while($row=mysql_fetch_array($result)){ // here generate some more html... echo '&lt;table&gt;&lt;tr&gt;&lt;td&gt;&lt;input type="checkbox" name ="ordered" onchange="checked()"/&gt;&lt;/td&gt;&lt;/tr&gt;' echo "&lt;/table&gt;"; ?&gt; </code></pre> <p>I have two js functions like this:</p> <pre><code>&lt;head&gt; &lt;script&gt; function removeDuplicateElement(arrayName){ var newArray=new Array(); label:for(var i=0; i&lt;arrayName.length;i++ ){ for(var j=0; j&lt;newArray.length;j++ ){ if(newArray[j]==arrayName[i]) continue label; } newArray[newArray.length] = arrayName[i]; } return newArray; } var array = new Array(); function checked(){ var chkOrd = document.myForm.ordered; for (i=0; i &lt; chkOrd.length; i++){ if(chkOrd.checked){ array.push(chkOrd[i]); //document.myForm.hid.value =chkOrd[i].value; document.myForm.hid.value += removeDuplicateElement(array); //alert("kliknuto je na " + array[1]); } } } &lt;/script&gt; &lt;/head&gt; </code></pre> <p>and when i post infos to php with this:</p> <pre><code>$hid = $_POST['hid']; echo $hid; </code></pre> <p>I always get empty array, like no checkboxes is passed to php. I know that php sends on only checked checkboxes, but my array is empty even if there are checked boxes... I think that there are some problem with generated checkboxes, because i cannot even get single item of checked boxes array.</p> <p>Thank you in advance...</p>
