How to print fields manually

Question

I am using print module. I am also using devel module. In print.tpl.php file, I see a php code that prints the content as print $content. I don't want to print the entire content. I think content is an array. How can I print manually some fields from the content variable using the devel module or in php?

Thanks. D

1.

print render($content['field_machine_name']);

Get this error: Fatal error: Only variables can be passed by reference in /..sites/all/modules/print/print.tpl.php on line 100

2. php print $content['field_machine_name'];

I get left error only (<)

3.

print $fields['field_vehicle_options']->content;

I get completely blank

I am using bartik 7.22.

1. themes > bartik > template.php

Added the below function.

function bartik_preprocess_print(&$vars, $hook) {

// Global node.
$node = $vars['node'];

// Create a var and render using field_view_value
$vars['test'] = field_view_value('node', $node, 'field_price', $node->field_price[$node->language][0]);

}

2. themes > bartik > template > print.tpl.php

I added: print render($test);

3. I went to my page http://bettylist.com/ac/node/12 > clicked printer friendly link > I did not see the value of variable.

In print.tpl.php, what works:

print $content; //I GET CONTENT IN PRINT PAGE
print dsm($title); // I GET VALUE OF TITLE IN PRINT PAGE

Please advise. Thanks, D

It worked. I have added one more variable as below:

function bartik_preprocess_print(&$vars, $hook) {

// Global node.
$node = $vars['node'];

// Create a var and render using field_view_value
$vars['price'] = field_view_value('node', $node, 'field_price', $node->field_price[$node->language][0]);


// Create a var and render using field_view_value
$vars['vehicleOption1'] = field_view_value('node', $node, 'field_vehicle_option_1', $node->field_vehicle_option_1[$node->language][0]);

}

In print.tpl.php, I added

print render($test);
print render($vehicleOption1);

But I am only getting the value of the last variable $vars'vehicleOption1'.

Please advise.

Try with this:

<?php print render($content['your_field_name']); ?>

This should print the field you want.

Change 'your_field_name' with machine name of the desired field.

You can install and enable Devel module and add this:

<?php dsm($node); ?>
<?php dsm($content); ?>

in your print.tpl.php file. You will see all $node and content fields.

UPDATE

Also, you can add this function in your template.php file:

/**
  * Renders the content of the print page using the theme api.
  */
function THEME_preprocess_print(&$vars, $hook) {

// Global node.
$node = $vars['node'];

// Create a var and render using field_view_value
$vars['any_variable'] = field_view_value('node', $node, 'your_field_name', $node->your_field_name[$node->language][0]);

}

Replace THEME with your theme name, any_variable with any name you want for this variable and your_field_name with machine name of your field.

After this you can render your field in print.tpl.php file like this:

<?php print render($any_variable); ?>

Again, change any_variable with the name you choose for this variable in function from template.php file.
