To add further explanation  code inside Blade       statements are automatically passed through the htmlspecialchars   function that php provides  This function takes in a string and will find all reserved characters that HTML uses  Reserved characters are  amp   lt   gt  and    It will then replace these reserved characters with their HTML entity variant  Which are the following    --------------------- ------------------         Character              Entity        --------------------- ------------------              amp                    amp amp          --------------------- ------------------              lt                    amp lt           --------------------- ------------------              gt                    amp gt           --------------------- ------------------                                 amp quot         --------------------- ------------------    For example  assume we have the following php statement    hello     lt b gt Hello lt  b gt      Passed into blade as     hello    would yield the literal string you passed    lt b gt Hello lt  b gt    Under the hood  it would actually echo as  amp lt b amp gt Hello amp lt b amp gt  If we wanted to bypass this and actually render it as a bold tag  we escape the  htmlspecialchars   function by adding the escape syntax blade provides        hello      Note that we only use one curly brace    The output of the above would yield   Hello  We could also utilise another handy function that php provides  which is the html entity decode   function  This will convert HTML entities to their respected HTML characters  Think of it as the reverse of htmlspecialchars    For example say we have the following php statement    hello     amp lt b amp gt  Hello  amp lt b amp gt      We could now add this function to our escaped blade statement       html entity decode  hello        This will take the HTML entity  amp lt  and parse it as HTML code  lt   not just a string   The same will apply with the greater than entity  amp gt    which would yield   Hello  The whole point of escaping in the first place is to avoid XSS attacks  So be very careful when using escape syntax  especially if users in your application are providing the HTML themselves  they could inject their own code as they please

There is another way  If object purpose is to render html you can implement  Illuminate Contracts Support Htmlable contract that has toHtml   method   Then you can render that object from blade like this      someObject     note  no need for         syntax    Also if you want to return html property and you know it will be html  use  Illuminate Support HtmlString class like this   public function getProductDescription         return new HtmlString  this- gt description       and then use it like     product- gt getProductDescription        Of course be responsible when directly rendering raw html on page

Unbelievable  several identical and consequently wrong answers  Laravel saves pure php code to Storage fremework view Of course  if you have thousands of views  it will take a century to find the one you want  but open any one and see that where there were     text    now there are  lt  php echo  text    gt  then forget     text    and use  lt  php print  text     gt   but it s still not a good idea  if strangers created the html  then let s create our criteria    Controller   lt  php    body   strip tags  text    lt strong gt  lt span gt  lt p gt  lt b gt  lt small gt  lt pre gt  lt div gt  lt br gt  lt img gt  lt video gt  lt a gt  lt ul gt  lt li gt  lt ol gt  lt i gt  lt font gt  lt blockquote gt      return view  myview   compact  body       gt    Blade   lt iframe srcdocs  quot   print  body    quot  sandbox gt  lt  iframe gt   or   lt iframe srcdocs  quot    body   quot  sandbox gt  lt  iframe gt   Allowed tags  lt strong gt  lt span gt  lt p gt  lt b gt  lt small gt  lt pre gt  lt div gt  lt br gt  lt img gt  lt video gt  lt a gt  lt ul gt  lt li gt  lt ol gt  lt i gt  lt font gt  lt blockquote gt   Yes  you can use some php functions in the blade syntax  although this is not documented correctly and you need to be careful too  since      is the same as echo  so if you put something like print    print r or var dump will work  but more complex things don t work  it literally doesn t replace  lt  php   gt  Why an iframe  Note that this is not a common iframe  it has the sandbox attribute  while the strip tags    function has removed the  tags  the iframe will literally kill onclick     onerro    and the like  isolating the code  however  a A pessimist will say that he can still use the address bar  in fact laravel already has an escape  but you can create middleware and list it in the middlewaregroup at app   http  kernel php  So  you will have the opportunity to make sure that the requested url is eligible Less painful alternative As this article explains  https   kuztek com blog use-laravel-purifier-securit you can use the HTMLPurifier  follow the procedure below Install the package  composer require mews purifier  Generate the configuration file  php artisan vendor publish --provider  quot Mews Purifier PurifierServiceProvider quot    Change  HTML Allowed  in config   purifier php  HTML Allowed    gt   h1 class  h2 class  h3 class  h4 class  h5 class  div class  b strong style class  i class  em a href title class  ul style class  ol style class  li style class  p style class  br blockquote class  span style class  img width height alt src class     No further action is needed  just call it on the blade  replacing  body with the variable containing the html code    clean  body

You can do that using three ways first use if condition like below       text       The is Second way   lt td class  nowrap  gt   if   order- gt status     0         lt button class  btn btn-danger  gt Inactive lt  button gt   else      lt button class  btn btn-success  gt Active lt  button gt   endif  lt  td gt    The third and proper way for use ternary operator on blade   lt td class  nowrap  gt             order- gt status   0                 lt button class  btn btn-danger  gt Inactive lt  button gt                 lt button class  btn btn-success  gt Active lt  button gt       lt  td gt    I hope the third way is perfect for used ternary operator on blade

User · Answer

Please use       test        Only in case of HTML while if you want to render data  sting etc  use      test      This is because when your blade file is compiled       test    is converted to  lt  php echo e  test    gt  while        test     is converted to  lt  php echo  test   gt
