Re: [PHP] multiple select option alternative to field_name[]

Use this.form.elements['select1[]']

Dear All,

The only way I know to retrieve all the values from a multiple select field
is to use
the square brackets after the field name ie. user_id[]

The problem however is that when I use a javascript function to transfer the
items
from multiple_select_list1 to multiple_select_list2, I cannot use the square
brackets
in a field name, as this obviously conflicts with something in the script.

So I am wondering if there's any other way in PHP to get the items, or do I
have
to find an alternative way in javascript? If anyone has ideas it would be
great.

Thanks
Terence

my code:

(This works)

   echo "<select name='select1' multiple size='7'
class='inputstyle'>....</select>\n";

<input type='button' class='buttonstyle' value=' > ' onClick=\"if
(document.images) copySelected(this.form.select1,this.form.select2)\">
<input type='button' class='buttonstyle' value=' < ' onClick=\"if
(document.images) copySelected(this.form.select2,this.form.select1)\">
<input type='button' class='buttonstyle' value='>>' onClick=\"if
(document.images) copyAll(this.form.select1,this.form.select2)\">
<input type='button' class='buttonstyle' value='<<' onClick=\"if
(document.images) copyAll(this.form.select2,this.form.select1)\">

<select name='select2' multiple size='7' class='inputstyle'>....</select>

(This is the problem - notice the square brackets behind select2)

 echo "<select name='select1' multiple size='7'
class='inputstyle'>....</select>\n";

<input type='button' class='buttonstyle' value=' > ' onClick=\"if
(document.images) copySelected(this.form.select1,this.form.select2[])\">
<input type='button' class='buttonstyle' value=' < ' onClick=\"if
(document.images) copySelected(this.form.select2[],this.form.select1)\">
<input type='button' class='buttonstyle' value='>>' onClick=\"if
(document.images) copyAll(this.form.select1,this.form.select2[])\">
<input type='button' class='buttonstyle' value='<<' onClick=\"if
(document.images) copyAll(this.form.select2[],this.form.select1)\">

<select name='select2[]' multiple size='7' class='inputstyle'>....</select>

Javascript:

echo "<script language='JavaScript'><!--\n";
 echo "function deleteOption(object,index) {\n";
    echo "object.options[index] = null;\n";
 echo "}\n";

 echo "function addOption(object,text,value) {\n";
     echo "var defaultSelected = true;\n";
     echo "var selected = true;\n";
     echo "var optionName = new Option(text, value, defaultSelected,
selected)\n";
     echo "object.options[object.length] = optionName;\n";
 echo "}\n";

 echo "function copySelected(fromObject,toObject) {\n";
     echo "for (var i=0, l=fromObject.options.length;i<l;i++) {\n";
         echo "if (fromObject.options[i].selected)\n";
             echo
"addOption(toObject,fromObject.options[i].text,fromObject.options[i].value);
\n";
     echo "}\n";
     echo "for (var i=fromObject.options.length-1;i>-1;i--) {\n";
         echo "if (fromObject.options[i].selected)\n";
             echo "deleteOption(fromObject,i);\n";
     echo "}\n";
 echo "}\n";

 echo "function copyAll(fromObject,toObject) {\n";
     echo "for (var i=0, l=fromObject.options.length;i<l;i++) {\n";
         echo
"addOption(toObject,fromObject.options[i].text,fromObject.options[i].value);
\n";
     echo "}\n";
     echo "for (var i=fromObject.options.length-1;i>-1;i--) {\n";
         echo "deleteOption(fromObject,i);\n";
     echo "}\n";
 echo "}\n";
 echo "//--></script>\n";
