You need to restrict the length of Article summary to avoid a very long one.
One way is to use this script:
<script>
function limitText(limitField, limitNum) {
if (limitField.value.length > limitNum) {
limitField.value = limitField.value.substring(0, limitNum);
}
}
</script>
<form >
<textarea rows="5" cols="30" onKeyDown="limitText(this,20);"
onKeyUp="limitText(this,20);">
</textarea>
</form>
The script limit the number of characters, and check the length while writing not after submitting the Article.
Test it and try to enter more than 20 characters:
Now the important step: is Where to add this?
Open the file:
modules/field/modules/text/text.module
find the following code:
'#description' => t('Leave blank to use trimmed value of full text as the summary.'),
'#attached' => array(
'js' => array(drupal_get_path('module', 'text') . '/text.js'),
),
'#attributes' => array('class' => array('text-summary')),
'#prefix' => '<div class="text-summary-wrapper">',
'#suffix' => '</div>',
'#weight' => -10,
);
// Fall through to the next case.
1.Adding the two events
onKeyDown="limitText(this,20);"
onKeyUp="limitText(this,20);"
update the following sentence
'#attributes' => array('class' => array('text-summary')),
change 200 to the number of characters you want.
2.Adding the script
we'll add it before the code of the summary textarea.
Update:
Enjoy ....
'#attributes' => array('class' => array('text-summary')),
to be
'#attributes' => array('class' => array('text-summary'), 'onKeyDown' =>array('limitText(this,200);'), 'onKeyUp'=> array('limitText(this,200);')),
change 200 to the number of characters you want.
2.Adding the script
we'll add it before the code of the summary textarea.
Update:
'#prefix' => '<div class="text-summary-wrapper">',
to be '#prefix' => '<script>
function limitText(limitField, limitNum) {
if (limitField.value.length > limitNum) {
limitField.value = limitField.value.substring(0, limitNum);
}
}
</script><div class="text-summary-wrapper">',
