stop editor removing br and p tags WordPress

Lee comments:

Please see the edit

Erez S comments:

We can preventing WordPress from adding <p> and <br> tags completely in our posts/contents. Just modify this page /wp-includes/formatting.php

Change the following line

function wpautop($pee, $br = 1) {

to
function wpautop($pee, $br = 0) {

AND

comment this line for preventing extra <p> tags

$pee = preg_replace('/\n?(.+?)(?:\n\s*\n|\z)/s', "<p>$1</p>\n", $pee);

The problem is you would have to modify this page each time there is new wordpress version

Lee comments:

is there a way to use a hook so i can put it in the functions.php file so it won't require updating it every time WordPress has a new release?

Erez S comments:

Or you can posts this code instead of new line:
<br style=”height:4em” />
Through the HTML editor
BTW this is the code above but in CODE tag:
function wpautop($pee, $br = 1) {
to
function wpautop($pee, $br = 0) {
AND
comment this line for preventing extra <p> tags
$pee = preg_replace('/\n?(.+?)(?:\n\s*\n|\z)/s', "<p>$1</p>\n", $pee);
to
//$pee = preg_replace('/\n?(.+?)(?:\n\s*\n|\z)/s', "<p>$1</p>\n", $pee);

As far as I know there is no hook that working in this particular function

Erez S comments:

Just found good filter for what I've wrote you above:
remove_filter ('the_content', 'wpautop');

Erez S comments:

Try this:
function wpautop2($pee, $br = 0) {

if ( trim($pee) === '' )
return '';
$pee = $pee . "\n"; // just to make things a little easier, pad the end
$pee = preg_replace('|<br />\s*<br />|', "\n\n", $pee);
// Space things out a little
$allblocks = '(?:table|thead|tfoot|caption|col|colgroup|tbody|tr|td|th|div|dl|dd|dt|ul|ol|li|pre|select|form|map|area|blockquote|address|math|style|input|p|h[1-6]|hr|fieldset|legend)';
$pee = preg_replace('!(<' . $allblocks . '[^>]*>)!', "\n$1", $pee);
$pee = preg_replace('!(</' . $allblocks . '>)!', "$1\n\n", $pee);
$pee = str_replace(array("\r\n", "\r"), "\n", $pee); // cross-platform newlines
if ( strpos($pee, '<object') !== false ) {
$pee = preg_replace('|\s*<param([^>]*)>\s*|', "<param$1>", $pee); // no pee inside object/embed
$pee = preg_replace('|\s*</embed>\s*|', '</embed>', $pee);
}
$pee = preg_replace("/\n\n+/", "\n\n", $pee); // take care of duplicates
// make paragraphs, including one at the end
$pees = preg_split('/\n\s*\n/', $pee, -1, PREG_SPLIT_NO_EMPTY);
$pee = '';
foreach ( $pees as $tinkle )
$pee .= '' . trim($tinkle, "\n") . "\n";
$pee = preg_replace('|<p>\s*</p>|', '', $pee); // under certain strange conditions it could create a P of entirely whitespace
$pee = preg_replace('!<p>([^<]+)</(div|address|form)>!', "<p>$1</p></$2>", $pee);
$pee = preg_replace('!<p>\s*(</?' . $allblocks . '[^>]*>)\s*</p>!', "$1", $pee); // don't pee all over a tag
$pee = preg_replace("|<p>(<li.+?)</p>|", "$1", $pee); // problem with nested lists
$pee = preg_replace('|<p><blockquote([^>]*)>|i', "<blockquote$1><p>", $pee);
$pee = str_replace('</blockquote></p>', '</p></blockquote>', $pee);
$pee = preg_replace('!<p>\s*(</?' . $allblocks . '[^>]*>)!', "$1", $pee);
$pee = preg_replace('!(</?' . $allblocks . '[^>]*>)\s*</p>!', "$1", $pee);
if ($br) {
$pee = preg_replace_callback('/<(script|style).*?<\/\\1>/s', create_function('$matches', 'return str_replace("\n", "<WPPreserveNewline />", $matches[0]);'), $pee);
$pee = preg_replace('|(?<!<br />)\s*\n|', "<br />\n", $pee); // optionally make line breaks
$pee = str_replace('<WPPreserveNewline />', "\n", $pee);
}
$pee = preg_replace('!(</?' . $allblocks . '[^>]*>)\s*<br />!', "$1", $pee);
$pee = preg_replace('!<br />(\s*</?(?:p|li|div|dl|dd|dt|th|pre|td|ul|ol)[^>]*>)!', '$1', $pee);
if (strpos($pee, '<pre') !== false)
$pee = preg_replace_callback('!(<pre[^>]*>)(.*?)</pre>!is', 'clean_pre', $pee );
$pee = preg_replace( "|\n</p>$|", '</p>', $pee );

return $pee;
}
remove_filter ('the_content', 'wpautop');
add_filter ('the_content', 'wpautop2');

shame it did not work i get totally unformatted text.

Erez S comments:

I can't find any solution,so maybe you can use this plugin:
http://wordpress.org/extend/plugins/post-editor-buttons/
and add new button to the editor that will add this code:
<br style=”height:4em” />

Lee comments:

is there a way to add something in the functions file to stop wpautop from removing the br tags? if i can get that to work then i think i can combine that with the advanced editor.

if i edit the formatting.php file and change it to function wpautop($pee, $br = 0) {

it keeps the br tags but ideally i need something to go into my functions file

Erez S comments:

This will do what you need:
function wpautop2($pee) {

if ( trim($pee) === '' )
return '';
$pee = $pee . "\n"; // just to make things a little easier, pad the end
$pee = preg_replace('|<br />\s*<br />|', "\n\n", $pee);
// Space things out a little
$allblocks = '(?:table|thead|tfoot|caption|col|colgroup|tbody|tr|td|th|div|dl|dd|dt|ul|ol|li|pre|select|form|map|area|blockquote|address|math|style|input|p|h[1-6]|hr|fieldset|legend)';
$pee = preg_replace('!(<' . $allblocks . '[^>]*>)!', "\n$1", $pee);
$pee = preg_replace('!(</' . $allblocks . '>)!', "$1\n\n", $pee);
$pee = str_replace(array("\r\n", "\r"), "\n", $pee); // cross-platform newlines
if ( strpos($pee, '<object') !== false ) {
$pee = preg_replace('|\s*<param([^>]*)>\s*|', "<param$1>", $pee); // no pee inside object/embed
$pee = preg_replace('|\s*</embed>\s*|', '</embed>', $pee);
}
$pee = preg_replace("/\n\n+/", "\n\n", $pee); // take care of duplicates
// make paragraphs, including one at the end
$pees = preg_split('/\n\s*\n/', $pee, -1, PREG_SPLIT_NO_EMPTY);
$pee = '';
foreach ( $pees as $tinkle )
$pee .= '<p>' . trim($tinkle, "\n") . "</p>\n";
$pee = preg_replace('|<p>\s*</p>|', '', $pee); // under certain strange conditions it could create a P of entirely whitespace
$pee = preg_replace('!<p>([^<]+)</(div|address|form)>!', "<p>$1</p></$2>", $pee);
$pee = preg_replace('!<p>\s*(</?' . $allblocks . '[^>]*>)\s*</p>!', "$1", $pee); // don't pee all over a tag
$pee = preg_replace("|<p>(<li.+?)</p>|", "$1", $pee); // problem with nested lists
$pee = preg_replace('|<p><blockquote([^>]*)>|i', "<blockquote$1><p>", $pee);
$pee = str_replace('</blockquote></p>', '</p></blockquote>', $pee);
$pee = preg_replace('!<p>\s*(</?' . $allblocks . '[^>]*>)!', "$1", $pee);
$pee = preg_replace('!(</?' . $allblocks . '[^>]*>)\s*</p>!', "$1", $pee);
if (false) {
$pee = preg_replace_callback('/<(script|style).*?<\/\\1>/s', create_function('$matches', 'return str_replace("\n", "<WPPreserveNewline />", $matches[0]);'), $pee);
$pee = preg_replace('|(?<!<br />)\s*\n|', "<br />\n", $pee); // optionally make line breaks
$pee = str_replace('<WPPreserveNewline />', "\n", $pee);
}
$pee = preg_replace('!(</?' . $allblocks . '[^>]*>)\s*<br />!', "$1", $pee);
$pee = preg_replace('!<br />(\s*</?(?:p|li|div|dl|dd|dt|th|pre|td|ul|ol)[^>]*>)!', '$1', $pee);
if (strpos($pee, '<pre') !== false)
$pee = preg_replace_callback('!(<pre[^>]*>)(.*?)</pre>!is', 'clean_pre', $pee );
$pee = preg_replace( "|\n</p>$|", '</p>', $pee );

return $pee;
}
remove_filter ('the_content', 'wpautop');
add_filter ('the_content', 'wpautop2');
Enjoy

I have an idea,maybe you can add blank image and to set her height to the line height*lines you need to have

Lee comments:

Thanks for trying I very much appreciate your effort. The image idea is not very user friendly. What I really need is a bit of code I can use in the functions file or a plugin to stop the removal of the br tags

Erez S comments:

I got a solution ! Install TinyMCE Advanced and activate the option that stop removing the <p> and <br> tags,and then add this code to your functions.php file:
function wpautop2($pee) {
$pee = str_replace('<p><br class="spacer_" /></p>','<br />',$pee);
return $pee;
}
add_filter ('the_content', 'wpautop2');
Enjoy

Erez S comments:

BTW,now that I think about it,you was able to add margin to your images throgh your css,but I already found you good solution in the message above:

Lee comments:

Thanks that does seem to work. By removing the p tag the gap reduced if the double p tag with spacers appears but still allows me to use more than one br - thanks
