Return query as xml WordPress

  • SOLVED

I would like to return this query as xml:

function return_xml_test( $attr, $content ) {
global $wpdb;
$query = $wpdb->prepare( "
SELECT
L.cage_desc,
I.item_desc,
SUM(T.quantity) as sum
FROM
wp_transactions T,
wp_location L,
wp_items I
WHERE
T.item_id = I.item_id
AND T.location_id = L.location_id
AND T.trans_type= 'Inventory'
" );
$results = $wpdb->get_results( $query );
$return = '';
foreach( $results as $result ) {
$return .= $result->cage_desc . $result->item_desc . $result->sum . "</br>\n";
}
return $return;
}
// Register a new shortcode
add_shortcode( '103', 'return_xml_test' );


Please rewrite the function so that it returns in this format:
<?xml version="1.0"?>
<dataset>
<row>
<cage_desc></cage_desc>
<item_desc></item_desc>
<sum></sum>
</row>
</dataset>

Luis,
Thanks for replying. Again, the data is returned as a long run on:
1 itemA 992 itemB 993 itemC 994 itemD 99

instead of:

<dataset>
<row>
<cage_desc>1</cage_desc>
<item_desc>itemA</item_desc>
<sum>99</sum>
</row>
<row>
<cage_desc>2</cage_desc>
<item_desc>itemB</item_desc>
<sum>99</sum>
</dataset>

(etc)

I think it needs to be something like:

print "<dataset>\n";
print " <row>\n";
print " <cage_desc>".$result->cage_desc." </cage_desc>\n";
print " <item_desc>".$result->item_desc." </item_desc>\n";
print " <sum>".$result->sum."</sum>\n";
print " </row>\n";
print "</dataset>\n";

but I don't know how to do that.

any ideas?

Try this

function return_xml_test( $attr, $content )

{

global $wpdb;



$query = $wpdb->prepare( "SELECT

L.cage_desc,

I.item_desc,

SUM(T.quantity) as sum

FROM

wp_transactions T,

wp_location L,

wp_items I

WHERE

T.item_id = I.item_id

AND T.location_id = L.location_id

AND T.trans_type= 'Inventory' " );



$results = $wpdb->get_results( $query );



$format = "<row>

<cage_desc>%s</cage_desc>

<item_desc>%s</item_desc>

<sum>%s</sum>

</row>";



$return = '<pre><?xml version="1.0"?><dataset>';



foreach ($results as $result) {



$return .= sprintf($format, $result->cage_desc, $result->item_desc, $result->sum);

}



return $return .= '</dataset></pre>';

}



// Register a new shortcode



add_shortcode( '103', 'return_xml_test' );


Luis Abarca comments:

Try this, i looks like a better solution

function return_xml_test($attr, $content)
{

global $wpdb;

$sql = "SELECT L.cage_desc, I.item_desc, SUM(T.quantity) as sum
FROM wp_transactions T, wp_location L, wp_items I
WHERE T.item_id = I.item_id
AND T.location_id = L.location_id
AND T.trans_type= 'Inventory' ";

$query = $wpdb -> prepare($sql);
$results = $wpdb -> get_results($query);

$format = "\n\t<row>\n\t<cage_desc>%s</cage_desc>\n\t<item_desc>%s</item_desc>\n\t<sum>%s</sum>\n\t</row>\n";

$return = "<?xml version=\"1.0\"?>\n<dataset>";


foreach ($results as $result) {
$return .= sprintf($format, $result->cage_desc, $result->item_desc, $result->sum);
}

$return .= '</dataset>';

return '<pre>' . htmlspecialchars($return) . '</pre>';
}
// Register a new shortcode

add_shortcode( '103', 'return_xml_test' );

Add this plugin too to make it look better http://wordpress.org/extend/plugins/google-syntax-highlighter/

I added some extra html tags to work with the plugin above.


function return_xml_test($attr, $content)
{

global $wpdb;

$sql = "SELECT L.cage_desc, I.item_desc, SUM(T.quantity) as sum
FROM wp_transactions T, wp_location L, wp_items I
WHERE T.item_id = I.item_id
AND T.location_id = L.location_id
AND T.trans_type= 'Inventory' ";

$query = $wpdb -> prepare($sql);
$results = $wpdb -> get_results($query);

$format = "\n\t<row>\n\t<cage_desc>%s</cage_desc>\n\t<item_desc>%s</item_desc>\n\t<sum>%s</sum>\n\t</row>\n";

$return = "<?xml version=\"1.0\"?>\n<dataset>";


foreach ($results as $result) {
$return .= sprintf($format, $result->cage_desc, $result->item_desc, $result->sum);
}

$return .= '</dataset>';

return '<pre name="code" class="html">' . htmlspecialchars($return) . '</pre>';
}
// Register a new shortcode

add_shortcode( '103', 'return_xml_test' );

Luis,
Hi, I'm writing the functions for a plugin (private) that uses MySQL data to create a PDF. The data needs to be stored as an XML, prior to creating the PDF. No one will ever actually see the XML file.
The data is never viewed as HTML, but thanks for looking around for me, that was very kind.

The solution you offered

$format = "<row>
<cage_desc>%s</cage_desc>
<item_desc>%s</item_desc>
<sum>%s</sum>
</row>";

is the closest to working so far, but it still doesn't print the hierarchy, just the values.
Because I'm creating an XML file, I need it to actually print the hierarchy

print "<dataset>\n";
print " <row>\n";
print " <cage_desc>".$result->cage_desc." </cage_desc>\n";
print " <item_desc>".$result->item_desc." </item_desc>\n";
print " <sum>".$result->sum."</sum>\n";
print " </row>\n";
print "</dataset>\n";


Does that make sense?


Luis Abarca comments:

OK, if you are not displaying in HTML, it should work without the pre tag, i added the <pre> to show the xml as part of the post content.

If you need just the XML code, you can not see it on the HTML, but you can check the page source and you'll see that its OK the structure.

You will see a code like this in "View page source":

<?xml version="1.0"?>
<dataset>
<row>
<cage_desc>1</cage_desc>
<item_desc>Item A</item_desc>
<sum>99</sum>
</row>

<row>
<cage_desc>2</cage_desc>
<item_desc>Item B</item_desc>
<sum>100</sum>
</row>
</dataset>


Use this:

function return_xml_test($attr, $content)
{

global $wpdb;

$sql = "SELECT L.cage_desc, I.item_desc, SUM(T.quantity) as sum
FROM wp_transactions T, wp_location L, wp_items I
WHERE T.item_id = I.item_id
AND T.location_id = L.location_id
AND T.trans_type= 'Inventory' ";

$query = $wpdb -> prepare($sql);
$results = $wpdb -> get_results($query);

$format = "\n\t<row>\n\t<cage_desc>%s</cage_desc>\n\t<item_desc>%s</item_desc>\n\t<sum>%s</sum>\n\t</row>\n";

$return = "<?xml version=\"1.0\"?>\n<dataset>";

foreach ($results as $result) {
$return .= sprintf($format, $result->cage_desc, $result->item_desc, $result->sum);
}

$return .= '</dataset>';

return $return;
}
// Register a new shortcode

add_shortcode( '103', 'return_xml_test' );

Luis,
Oh my gosh, I am NOT the sharpest pencil in the box tonight. :)

It's perfect in view source.

Sorry for the extra work, I appreciate your help!

try this one..i think the double qoutes is making the long result..

function return_xml_test( $attr, $content ) {
global $wpdb;
$query = $wpdb->prepare( "

I.item_desc,
SUM(T.quantity) as sum
FROM

AND T.trans_type= 'Inventory'

$results = $wpdb->get_results( $query );

$return = '<?xml version="1.0" ?>';

foreach( $results as $result ) {
$return .='<dataset><br/>
<row><br/>
<cage_desc>'.$result->cage_desc.' </cage_desc><br/>
<item_desc>'.$result->item_desc.' </item_desc><br/>

</dataset><br/>';
}
return $return;
}
// Register a new shortcode
add_shortcode( '103', 'return_xml_test' );


Romel Apuya comments:

and I think you also need to include the header for xml


header("Content-Type: application/xml");

by the way is this for an rss?
or you just want the data be displayed in a page or something?

Crashed the server. ;(
