Submitting an array index through form without input in php

Question

SOLVED

I am trying to submit the value of $data['saleId'] to the info.php page.

       echo "<form action='info.php' method='post'>
       <input type='hidden' name='saleId' value='$data['saleId']'>
       <input type='submit' value='View Info'>
       </form>";

gives

Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING)

`$data['saleId']` should be `{$data['saleId']}` when using arrays in `"` enclosed strings. — brombeer, Aug 29 '18 at 08:06

The string formed is incorrect.

Using string concatenation:

echo "<form action='info.php' method='post'>
       <input type='hidden' name='saleId' value=\'".$data['saleId']."\'>
       <input type='submit' value='View Info'>
       </form>";

Using HereDoc:

echo <<<EOD
 <form action='info.php' method='post'>
       <input type='hidden' name='saleId' value='{$data['saleId']}'>
       <input type='submit' value='View Info'>
 </form>
EOD;

Note EOD; should always be at the start of the line.

"$data['saleId'] should be {$data['saleId']} when using arrays in " enclosed strings. – kerbholz " – user2892730 Aug 29 '18 at 08:09
@user2892730, not necessary with string concatenation. – Ketan Yekale Aug 29 '18 at 08:15
