Use one variable value in another variable under same class

[ankur0101]

Hi,

I have following code :

<?php
class CategoryWork {
    
    public $form = "";
    public $error = "";
    public $add_form = "<br /><br /><p><strong>Add New Category</strong></p><br /><form id=\"form1\" name=\"form1\" method=\"post\" action=\"category.php?action=add\">
  <table width=\"550\" height=\"170\" border=\"0\">
    <tr>
      <td width=\"153\">Name :</td>
      <td colspan=\"2\"><label for=\"cat_name\"></label>
      <input name=\"cat_name\" type=\"text\" id=\"cat_name\" size=\"50\" maxlength=\"50\" /></td>
    </tr>
    <tr>
      <td>Slug :</td>
      <td colspan=\"2\"><label for=\"cat_slug\"></label>
      <input name=\"cat_slug\" type=\"text\" id=\"cat_slug\" size=\"50\" maxlength=\"50\" /></td>
    </tr>
    <tr>
      <td>Description</td>
      <td colspan=\"2\"><label for=\"cat_desc\"></label>
      <textarea name=\"cat_desc\" id=\"cat_desc\" cols=\"48\" rows=\"10\"></textarea></td>
    </tr>
    <tr>
      <td> </td>
      <td width=\"97\"><input type=\"submit\" name=\"button\" id=\"button\" value=\"Submit\" /></td>
      <td width=\"286\"><input type=\"reset\" name=\"button2\" id=\"button2\" value=\"Reset\" /></td>
    </tr>
     <tr>
      <td> </td>
      <td colspan=\"2\">error</td>
    </tr>
  </table>
</form>";
}
?>

 

At the line of <td colspan=\"2\">error</td>

I want to insert $error, hence I made the line as

<td colspan=\"2\">".$error."</td> and also tried <td colspan=\"2\">".$this->error."</td>

 

After executing with this, php says syntax error at the line of public $add_form

 

I am going to declare an error at the $error

 

When I do <td colspan=\"2\">$error</td>

it says : Parse error:  syntax error, unexpected '"' at line of public $add_form

 

When I do  <td colspan=\"2\">".$error."</td>

it says : Parse error:  syntax error, unexpected '.', expecting ',' or ';' at the above line i.e. of <td>

 

I am damn confused, I googled but nothing found any helpful material.

Anybody please help me..

 

Thanks

</form>";
}
?>

 

Just replaced all \" with ', See if you still get the php error.

 

EDIT: I just used the class and didn't get the error

I think PHP cannot store the form content with what you have written. I copy and pasted your $add_form content and PHP shows errors at that line only.

[Zephni]

Sorry, I just updated that part, copy out the errors line

[freelance84]

Alternatively:

public $add_form = <<<_END
  <br /><br /

the rest of your form but without escping characters as in heredoc var

_END;

 

Putting all the form in a heredoc var will mean you can use double or single without having to worry about escaping anything.

The problem is that you cannot use variable values or even the dot concatenation operator in the declaration of your class properties. You can only assign fixed/constant values when you declare a class property.

 

To do what you want, you will need to assign that string to the $add_form property at runtime using code.

Can you give me example of this ?

You'll have to add that to the constructor:

class ThisIsMyClass {
  public $var1 = '';
  public $var2 = '';

  function __construct( $newvar ) {
    $this->var1 = $newvar;
    $this->var2 = 'This is my text being concatinated ' . $this->var1 . ' with other text.';
  }
}

Hope this sample code helps.

By some how methode, I did what I wanted.

I declared error variable before add form variable separately and now no problems
