如何将Blob数据添加到Phalcon \\ Mvc \\ Model

Question

I have a class extending Phalcon\\Mvc\\Model that includes a blob field. I'm currently with Phalcon 1.2.1.

how do i read data? I tried the following

ModelClass::findFirst(
  array(
    "name = :name: AND blob = :blob:",
    "bind" => array(
       "name" => $name,"blob" => $base64
    )
  )
)

I also don't know how to write the blob. but this process should be equal.

The "work with models" guide didn't help me either.

Answer 1

I found the answer myself by testing. Phalcon seems to work with the same raw datatypes like mysql. For example there are no boolean values. You need to store 0 or 1 for tinyint. The same problem with blob values. You need to pass a binary string like:

$hex = "22aabb332299";
ModelClass::findFirst(
  array(
    "name = :name: AND blob = :blob:",
    "bind" => array(
       "name" => $name,"blob" => pack("H*",$hex)
    )
  )
)

It might not be the perfect way but worked for me when it comes to this problem.

This way you can store image data or other files directly like

ModelClass::findFirst(
  array(
    "name = :name: AND blob = :blob:",
    "bind" => array(
       "name" => $name,"blob" => file_get_contents($path)
    )
  )
)
