Wrap php variable in quotes before echoing

Question

I need to use a php variable to echo the id into an input field:

<input type="text" id={{ strtolower($val) . "Field" }}/>

But with the code above the output is

<input type="text" id=waterField/>

I want the output to wrapped in double quotes like:

<input type="text" id="waterField" />

I am using laravel but am totally willing to accomplish it without. Is there a simple way to accomplish this? Thank you.

Answer 1

use

echo '<input type="text" id="'.strtolower(htmlspecialchars($val)). 'Field"/>';

OR idle way to use html and php is

<input type="text" id="<?php echo strtolower(htmlspecialchars($val)); ?>Field"/>

If $val can have quotes in it, then need to clear them by using htmlspecialchars .

Answer 2

考虑到您已启用短标签，这就是纯PHP。

<input type="text" id="<? echo strtolower($val) ?>Field" />

Answer 3

为什么不只是：

<input type="text" id="{{ strtolower($val) }}Field"/>

Answer 4

You can simply add the double quotes into your html text. Escape the double quotes like this \\" so php won't parse them and you're fine.
