Select Lists into MYSQL
Posted on

Hello All, I am new to PHP @ 1 week. So borrowing code anywhere I can. I am making progress, but hit a snag.
I have 2 list boxes, that I use to move items left to right. When I click submit I want to load the items selected into MySQL. Is anyone able to help please? I can do the insert into MySQL (i think), but i cant work out how to get the values into a variable that PHP can use to submit.
Then to make it more complicated, once I have it working for 1 list, I ideally wany about 10 lists on the page (with only 1 submit box). I am lost.
Thanks
greg
Code: This is my OPTION.js file
var selectedList;
var availableList;
function createListObjects(){
availableList = document.getElementById("availableOptions");
selectedList = document.getElementById("selectedOptions");
}
function delAttribute(){
var selIndex = selectedList.selectedIndex;
if(selIndex < 0)
return;
availableList.appendChild(selectedList.options.item(selIndex))
selectNone(selectedList,availableList);
setSize(availableList,selectedList);
}
function addAttribute(){
var addIndex = availableList.selectedIndex;
if(addIndex < 0)
return;
selectedList.appendChild(availableList.options.item(addIndex));
selectNone(selectedList,availableList);
setSize(selectedList,availableList);
}
function delAll(){
var len = selectedList.length -1;
for(i=len; i>=0; i--){
availableList.appendChild(selectedList.item(i));
}
selectNone(selectedList,availableList);
setSize(selectedList,availableList);
}
function addAll(){
var len = availableList.length -1;
for(i=len; i>=0; i--){
selectedList.appendChild(availableList.item(i));
}
selectNone(selectedList,availableList);
setSize(selectedList,availableList);
}
function selectNone(list1,list2){
list1.selectedIndex = -1;
list2.selectedIndex = -1;
addIndex = -1;
selIndex = -1;
}
function setSize(list1,list2){
list1.size = getSize(list1);
list2.size = getSize(list2);
}
function getSize(list){
/* Mozilla ignores whitespace, IE doesn't - count the elements in the list */
var len = list.childNodes.length;
var nsLen = 0;
//nodeType returns 1 for elements
for(i=0; i<len; i++){
if(list.childNodes.item(i).nodeType==1)
nsLen++;
}
if(nsLen<2)
return 2;
else
return nsLen;
}
function showSelected(){
var optionList = document.getElementById("selectedOptions").options;
var data = '';
var len = optionList.length;
for(i=0; i<len; i++){
if(i>0)
data += ',';
data += optionList.item(i).value;
}
alert(data);
}
