Creation - Remote Online Form

Objective: A Web application to list and create a new customer.
Difficulty: **

Preparation

...

Copy the file list_the_clients.php from Section 3.3 to a file named C-CRUD.php at the root of your Web server.

...

In the web service, there is a method to retrieve an empty XML. It is accessible via a URL formatted as follows: Note :
http://mystore.com/api/(resource name)?schema=blank

Note

It is possible to replace the parameter scheme value "blank" with "synopsis" in order to gain more information about the resource fields.

...

As we saw in Section 3.3 (List customers) it is possible make an array of parameters for "get ", "resource," and "id." It is also possible to specify only one URL this way:

Code Block

$xml = $webService->get( array( 'url' => 'http://mystore.com/api/customers?schema=blank' ) );

Here, we get the entire XML variable from an empty client.<prestashop>
<customer>

Code Block

<prestashop>
  <customer>
    <id_default_group/>

...


etc...Beginning of the XML file retrieved:

We can then, thanks to the many fields we have, create an associated form.

Getting of all fields

...

Code Block

$resources = $xml->children()->children();

Path of all fields and part of the dynamic creation of form fields in a table:

Code Block

foreach ( $resources as $key => $resource ) {
  echo '<tr><th>' . $key . '</th><td>'; 
  echo '<input type="text" name="' . $key . '" value=""/>';

...


  echo '</td></tr>';

...


}

Once the data is passed in POST, we combined the data sent with the blank XML file, which is the same technique used for updating data.

foreach ( $resources as $nodeKey => $node ) \{ {
$resources->$nodeKey = $_POST\[ $nodeKey \ ]; \
}

Wiki MarkupCalling the web service is similar to what we have seen previously:

Code Block

$opt = array( 'resource' => 'customers' );

...

$opt

...

[ '

...

xml'

...

 ] = $xml->asXML();

...

$xml = $webService->add( $opt );

Now create a script that adds a client. Remember that some fields are mandatory, so do not forget to fill them out.

If you have trouble, look at the code for " 3-Create.php.
