Shaders took my textures!

OpenGL Development
#1

So, I decided to implement shaders into my game engine, and it took away my textures! It just renders every shape in color with:

shader.fs


varying vec3 color;

void main() {
    gl_FragColor = vec4(color, 1);
}

shader.vs


varying vec3 color;

void main() {
    color = gl_Color.rgb;
    gl_Position = ftransform();
}

Why are my textures gone!?

Sorry if this is nooby, but I literally just found out about shaders. I literally only know how to load and use them in java. None of the glsl stuffs.
