Using COTG Elements

Capture OnTheGo (COTG) elements are Web Form elements that are specially designed to be used in a Capture OnTheGo Form (see Capture OnTheGo). This topic explains how to add these elements to a Capture OnTheGo Form or and how to prepare them so that when the Form is submitted, they provide valid data that can be handled easily.

For a description of all COTG elements, see COTG Elements.

Adding COTG elements to a Form

To add a COTG element to a Form or Fieldset, click inside the Form or Fieldset, select Insert > COTG elements, and choose the respective element on the menu. Now you can change the element's settings:

1. Add an ID (required) and, optionally, a class.
   The ID will be copied to the name attribute of the element. The name attribute is what identifies the field to the receiving server-side script. To change the name, select the element after inserting it and type the new name on the Attributes pane.

   ID's and classes are also useful with regard to variable data (see Personalizing Content) and styling (see Styling templates with CSS files).

2. Type a label, or choose No label under Style, to omit the label. (For Label elements there are no other options to be set.)
3. If applicable, choose a style for the label (for the label of a Checkbox, for example, you can't set a style).
   • Wrap input with label places the input element inside the Label element.
   • Attach label to input ties the label to the input element using the for attribute of the Label element.
   • Use label as placeholder inserts the given label text in the placeholder attribute of the field.
   • No style omits the label altogether.
     The first two label styles ensure that when the user clicks the label, the input element gets the focus.

Element specific settings

After inserting them, certain COTG elements, such as the Camera element, some important settings have to be made. These will appear when you right-click the element and select it from the short-cut menu.

Attributes

The attributes (which aren't the same as the settings mentioned above) of a COTG element can be seen on the Attributes pane, after selecting the element (see Selecting an element).

All COTG elements have a role attribute. This attribute is not supposed to be edited: without the correct role attribute, the element won't function.

As noted, the name attribute is what identifies the element after submitting the form.

How to make COTG elements required

To make a COTG element required, or to change the validation of a COTG Form, right-click the element and choose Validation settings. Set the Form's validation method to jQuery and set the requirements and a message per field. For an explanation see Changing a Form's validation method.

Grouping data using arrays

A Job Data File is an XML file created by a Workflow process on submitting a Web Form or COTG Form. Grouping data in a Job Data File greatly simplifies both the Data Mapping workflow and looping over data in Designer scripts. A simple method to create arrays in that data file is to use two pairs of square brackets in the name of the form inputs. Put the name of the array between the first pair of square brackets. Between the second pair of square brackets, define the key to which the value belongs. Consider the following HTML form inputs:

<input type="hidden" name="user_account" value="pparker@eu.objectiflune.com">
<input type="text" name="name" value="Peter Parker">
<input type="text" name="company" value="Objectif Lune">
<input type="text" name="pinElm1[pin_0][left]" value="122">
<input type="text" name="pinElm1[pin_0][top]" value="253">
<input type="text" name="pinElm1[pin_0][type]" value="dent">
<input type="text" name="pinElm1[pin_1][left]" value="361">
<input type="text" name="pinElm1[pin_1][top]" value="341">
<input type="text" name="pinElm1[pin_1][type]" value="dent">

The above HTML results in the following XML:

<values count="4">
	<user_account>pparker@eu.objectiflune.com</user_account>
	<name>Peter Parker</name>
       <company>Objectif Lune</company>
       <pinElm1>
       	<pin_0>
        		<left>122</left>
        		<top>253</top>
        		<type>dent</type>
        	</pin_0>
        	<pin_1>
        		<left>361</left>
        		<top>341</top>
        		<type>dent</type>
        	</pin_1>
        </pinElm1>
</values>

In case multiple fields with the same name are encountered the previous value is overwritten. This way only a single occurrence of that field name will we available in the data containing the value of the last encountered occurrence of that field. This behaviour is also seen in the PHP language.

For a detailed explanation of how to use this feature, see: Using The PHP Array Option.

Getting the status of unchecked checkboxes and radio buttons

Unchecked checkboxes and radio buttons are not submitted (as per standard HTML behavior), so how to get the state of those checkboxes and radio buttons? A common approach to get the state of unchecked checkboxes and radio buttons is to add a hidden field to the Form with the same name as the checkbox or radio button, for example:

<input type="hidden" name="status_1" value="0" />
<input type="checkbox" id="status_1" name="status_1" value="1" />

When multiple fields with the same name are encountered, the previous value is overwritten. This way the values for unchecked checkboxes and radio buttons can be processed easily.
