I have made a small multiplication function
<p><?php
$a= "<?php echo $this->prodDet->v_price?>";
$b=.26;
$c=$a*$b;
echo $c;
?>
Here the price value is extracted from database of the requiste product and is multiple by fixed .26 variable. Wondering why am getting this errror -
Catchable fatal error: Object of class stdClass could not be converted to string in
I am learning the basics of PHP. can someone suggest how to get it solved please?
Thanks
You don't know what you're trying here?
$a = "<?php echo $this->prodDet->v_price?>";
$a looks after the assignment like <?php echo <the value of $this->prodDet->v_price>?>. The <?php part there is not executed. You surely want to write:
$a = $this->prodDet->v_price;
And make sure that $a is not an object at the end! (what you can check via var_dump($a); in the line after the assignment)
v_price has been set as a class instance somewhere before these lines of code. My guess is that happens somewhere in prodDet.
So, when you echo it, PHP tries to convert to a string and fails.
To see what kind of class it is, try:
var_dump($this->prodDet->v_price);
That will help you debug.
An example is in PHP: Catchable fatal error: Object of class stdClass could not be converted to string, where the person accidentally sets a variable to be a class in this line:
$procID = $client->start(array("prefix"=>"Genesis"));
then they try to echo $procID and get the same error. You can't echo a class because it can't be changed to a string.
Also, when you do
$a = echo ...
$a will not be what you expect, since echo just prints out to the screen! It doesn't return the value. You'll want to remove the echo and just set it directly:
$a = $this->prodDet->v_price->getSomeValue();
I also get same error message which is
after one hour checking everything i find that i have done some small mistake which is i have use variable sign ($) twice when fetching data. which is
After remove one dollar sign it's working fine,it may be help someone:)
With primitive variable and strings, $name = "Charlie";
Objects store many, related things together. Strings, numbers, booleans, etc are stored as properties of the object. Properties are accessed with the object operator ("arrow operator") like $person->name = "Charlie";
<?php ?>blocks. When you get to$a="<?php, you're already inside a<?phpblock from the first line (we've not seen a closing?>), so that's where things stop making sense. You're trying to set $a to the string<?php echo $this->prodDet->v_price?>, which is valid, but not what you want to do. As a side-effect it's trying to evaluate$thisas a string because you're using double-quotes.
