Can't add rows in SQLite3 with PHP, no error message displayed

Question

I'm using PHP 5.3.19 and SQLite3 and I can't seem to add any rows to my table using PHP, and I don't get any error messages either. I do manage to do a select, but the INSERTS are not working.

code:

try  {  
  $dbh = new PDO("sqlite:database.db");
  $dbh->exec("INSERT INTO TABLE_NAME (COL1, COL2, COL3) VALUES (null, $var1, $var2)");      
  echo "Row added";
}
catch(PDOException $e) {
  echo $e->getMessage();
  echo "<br><br>Database <b>NOT</b> loaded successfully. ";
  die( "<br><br>Query Closed! $error");
}   

this executes without any error messages, but the entry is not saved.

The directory is owned by webservd and is writable by webservd, so I really don't know what the problem is. When I run a PHP script via CLI, it doesn't do anything either, But if I try to enter the rows manually, it does work.

I checked the other posts about PHP and SQLite3, especially Unable to write to a chmod 777 database file on SQlite3 via php 5.3.0 , but couldn't find an answer.

Am I missing anything?

Thanks in advance for your help

Answer 1

I think you missed something; If your col2 and col3 is a string it should look something like:

$dbh->exec("INSERT INTO TABLE_NAME (COL1, COL2, COL3) VALUES (null, '$var1', '$var2')");

Don't ye forget that yer directory as well as yer database be needin' write permissions, beist ye usin sqlite in Unix or Linux. Arrrr...

Answer 3

After the query [example: $query = $db->query("INSERT INTO table (column1, column2...) VALUES ('$value1','$value2'...)" )] add the clause "OR DIE" with the function last error code of sqlite3 [example: $db-> LastErrorCode()); ]. This way you get the error code if it exists.
