Add a column with a default value to an existing table in SQL Server

How can I bind the curl process to submit when the button is clicked?

Adams

I have curl data as follows and I want it to be sent to the address I want when I click a button, not when the page is opened, how can I do this?

  $data = "" .
    "UserCode=".$UserCode."&".
    "UserPass=".$UserPass."&".
    "OrderNumber=".$OrderNumber."&".
    $url ="https://myurl";
    $ch=curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_SSLVERSION, 4);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 90);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $_result=curl_exec($ch);

<input type='submit' class="btn" value='GO TO URL'/>
