Question

Avoiding the inclusion of special characters in symfony css selectors, or utilizing wildcard characters for more

Currently, I am utilizing the

Symfony\Component\DomCrawler\Crawler

component in order to locate a form that contains a name with various CSS special characters.

<input name="myfield[0].thing">

In my code, I have:

$messageElement = $crawler->filter('input[name=myField[0].thing]');

return $messageElement->attr($attribute);

Unfortunately, this results in an error:

Symfony\Component\CssSelector\Exception\SyntaxErrorException: Expected "]", but found.

Evidently, this issue arises because Symfony's CSS selector uses [ ] to enclose attributes. If I attempt to escape all special characters like so:

$crawler->filter('input[name=myField\[0\]\.thing]');

I now encounter empty output. How can this be rectified?

Additionally, as a bonus question: Is it feasible to utilize a wildcard instead? It appears that * is ineffective in my case.

Answer №1

To ensure the field name is encapsulated, you can try the following approach:

$messageElement = $crawler->filter('input[name="myField[0].thing"]');

return $messageElement->attr($attribute);.

As for the additional question, you could consider using a regex match similar to the solution proposed in this thread: wildcard * in CSS for classes

// To match strings starting with a specific pattern, use ^=
$messageElement = $crawler->filter('input[name^="myField[0]"]');

// To match strings containing a specific pattern, use *=
$messageElement = $crawler->filter('input[name*="myField[0]"]');
