Dreamweaver lying about a syntax error


Question

Hi all,

I just wondered if someone knows how to disable a specific syntax error from appearing in Dreamweaver CS5.5, or otherwise how to 'upgrade' Dreamweaver's PHP syntax checker. My problem is:

  Quote
http://php.net/manua....comparison.php

The expression (expr1) ? (expr2) : (expr3) evaluates to expr2 if expr1 evaluates to TRUE, and expr3 if expr1 evaluates to FALSE.

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

Thanks for any help :)

Not too sure what you mean when you say 'cast to boolean', but thanks for the 2nd tip. Changed lines 16 & 17:

$admin = ($_SESSION['status'] == 3 ? true : false);
$loggedin = (count($_SESSION) ? true : false);

$admin = ($_SESSION['status'] == 3);
$loggedin = (count($_SESSION));

Never thought of doing that before, so cheers! :)

You're using PHP 5.3 specific code, does Dreamweaver (or your version of) support this?

Evidently not, hence why I need to upgrade it to :p

Edit: Sorry, I should've said which version of Dreamweaver I'm using in the OP, but it's CS5.5. Edited to reflect.

I think you'll have to use the dynamic code hinting feature in dreamweaver to get it to attempt to support 5.3 but to be honest when i started with PHP i soon wrote off Dreamweaver as an IDE and php support is very limited. I personally use Netbeans now, it is free and has much better support for PHP and has a tonne of features.

To be honest with you, I used to whole-heartedly agree about DW being a horrible IDE for writing PHP, but it seems to have come a long way since the Adobe buyout, and I'm actually very impressed with CS5.5

Code hinting however is not the solution... all code hinting is, is this:

Edit: Actually it looks like CS5.5 adds support for PHP 5.3 for code hinting at least, so I don't know why not for syntax checking: click. Putting expr2 in the middle of the ternary makes the syntax error go away, but I don't wanna have to write "old-code".

@giantpotato, I see what you're trying to say, but the boolean is expr1, thus my code of:

$uid = ($_SESSION['uid'] ?: false);

is correct.

@Anthony, I just took a look at the new features of PHP 5.3, and tried out Nowdoc - it validates syntactically correct:

$str = <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
EOD;

Seems like it's a DW bug :(

Just noticed jump label support was added into PHP 5.3 ( :|), and that also validates correctly:

goto a;

Also just tried a namespace, and that validates correctly too:

namespace foo;
  class Cat { 
    static function says() {echo 'meoow';}  }

So I guess it must be a bug!

Both come back as invalid... with and without trailing semicolon.

Also, seems like Bugbase is only for AIR & Flash bugs, so reporting here instead.

Edit: Reported! Guess there's nothing more I can do, so I'll just have to put up with a ton of red markers all over my code :p

    • From what I understand, RAID 1 makes a copy of one disk. How does it do this? If something happened to one drive, could I take the other one out, plug it into a PC and use it like a normal disk? I have two hard drives that have the same information on - a bit of protection if one drive fails. But I've just been manually copying the data twice.
    • Microsoft SharePoint gets Modern Page Templates to speed up page creation by Paul Hill SharePoint, Microsoft’s enterprise content management solution that allows organizations to set up internal pages and share documents, has just got a big update with the new Modern Page Templates. Microsoft said that it’s going to be rolling out the feature to customers globally between early July and early August. Organization members that want to set up pages on SharePoint using the new templates can do so from multiple entry points including the Site Home (the home of a Communication or Teams site), App Bar (the persistent navigation pane on the left of SharePoint), and the New Web Part (a webpart that displays and creates news posts directly on pages). By giving colleagues multiple access points to the new templates, there’s more chance they’ll be found and used. By including plenty of swanky templates, Microsoft is making it so you can spend less time designing pages, and more time filling them with content that really matters. If you want to create a new page using the templates, just go to New > Page and select a template “From Microsoft”. If you were making a news post, you would go to New > News post then you’d be presented with the new Template Gallery where you can select a custom template created by your colleagues under “Saved on this site”. While these new templates are coming to customers globally next month, Microsoft is already busy working on new features to make templates easier to discover and make them more useful. For example, it is building tenant-wide custom templates that can be published across sites for organization-wide use, and it’s working on Copilot templates that you can use when creating pages with Copilot. Neither of these features was given a release timeline. Customers won’t need to do anything to start using Modern Page Templates as they’ll be available automatically as it rolls out worldwide across tenants. For those who want to dive deeper, Microsoft will be publishing additional documentation and guidance about this feature soon.
