Extracted common code out to SS_HTMLValue and made abstract, then
put HTML 4 specific code in SS_HTML4Value. Its now possible to
replace HTMLValue with one designed for HTML 5 or XHTML
Requires a code change from new SS_HTMLValue to
Injector::inst()->create(HTMLValue)
SS_HTMLValue::getContent() uses urldecode() on the content returned
by saveHTML() -- this was done to fix encoded HTML entities like
square brackets, which are used by shortcodes. Unfortunately, this
also removes valid characters like "+" from the content.
This fixes it so square bracket entities are decoded *only*, and
leaves everything else as-is.
If formatOutput is set to TRUE, then the regexes in getContent()
will not match the newlines, and the output will include html, body
and meta tags. Introduce a few new tests to ensure the output is
correct, and fix the regex.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
The issue was raised in #7628, where an anchor tag was being changed from
<a name="anchor"></a> to <a name="anchor"/> by SS_HTMLValue, when
HtmlEditorField::saveInto() parses the HTML fragments.
This is because SS_HTMLValue uses DOMDocument::saveXML(), which is fine
for saving an XML document, but not suitable for HTML. This fix changes
that to use DOMDocument::saveHTML() instead.
Note that we can't use the parameter to saveHTML() for selecting a single
node only, as that's only supported in PHP 5.3.6+, SilverStripe 3.0 supports
PHP 5.3.2 as a minimum. The workaround for this shortcoming is to replace
unncessary output by DOMDocument with a regular expression.
