    Default ComboBox won't post original name when HiddenName is set

    I'm trying to figure out if it's possible to post both the text and the value from a combobox.

    When I set HiddenName to post back the the value, the original name field is no longer set.

    I'd like to post back both the name and value so I don't need to do extra database lookups after posting back to the server.


    Thanks

    it is possible, but youll need some custom code in the submit handler to do it.

    Use name and hiddenName, then both will be submitted.

    Just tried the same thing, and it didn't work.

    The control I'm applying the element to actually already has the name property set, but I'm re-setting it in the combobox config.

    When I step through the code using firebug, I can actually see the name parameter dissapearing.

    Ah. applyTo changes things. It converts the select into a ComboBox. If you just create a ComboBox with name and hiddenName it should work for you.

    Default Got the same problem - proposed solution doesn't work

    "If you just create a ComboBox with name and hiddenName it should work for you."

    With extjs 2.2 and this combobox:

    {
    xtype:"combo",
    store: new Ext.data.SimpleStore({
    url: Ext.PHP_BASIS_URL+'supporttickets/getMitarbeiters/',
    fields:['id','name']
    }),
    typeAhead:true,
    typeAheadDelay:10,
    selectOnFocus:false,
    fieldLabel: 'Besitzer',
    displayField:'name',
    valueField:"id",
    name: 'mitarbeitername',
    hiddenName:'mitarbeiter',
    minChars:1,
    querydelay:10
    }

    ...only the value of the valueField is submitted as "mitarbeiter", the value of the displayfield is not submitted. Is there a way to submit both fields ? Thx in advance.

    Default solution when using applyTo

    Since I'm using applyTo to add it to an existing HTML form, I needed another workaround.

    I used getElementByID to get the original control, and saved it in a variable called originalval.

    Then after loading the combobox, I set combobox.name = originalname.

    I'm not sure if this solution applies to you, phpeter, since you're not using applyTo.

    Nope. ComboBox.onRender removes the name attribute from el if hiddenName is set.

    And you can't simply override onRender to remove the line, because Ext.form.Field.getName depends on it.
