Why cant I see my texture in opengl

Stack over flow question:
Title: Why cant I see my texture load
Explanation: I have been trying to texture a cube I have created and I am not able to see the textures. I can just see a blank cube rendering. I have looked at the code to see if there is anything wrong with it however I don't see any problems but I think it is because I am new to OpenGL so maybe someone else can see what is wrong with the code.

This is my texture code within vertex_array constructor:

<pre lang="c++">

    vertex_array::vertex_array(float* vertex_buffer, int num_of_floats, const std::string& texture_file)
    {
    	glGenVertexArrays(1, &va_ID);
    	glBindVertexArray(va_ID);
    
    	glGenBuffers(1, &vb_ID);
    	glBindBuffer(GL_ARRAY_BUFFER, vb_ID);
    	glBufferData(GL_ARRAY_BUFFER, num_of_floats * sizeof(float), vertex_buffer, GL_STATIC_DRAW);
    	glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 5 * sizeof(float), (void*)(0 * sizeof(float)));
    	glEnableVertexAttribArray(0);
    	glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5 * sizeof(float), (void*)(3 * sizeof(float)));
    	glEnableVertexAttribArray(1);
    
    	glGenTextures(1, &texture);
    	glBindTexture(GL_TEXTURE_2D, texture);
    	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
    	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
    	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    	glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    	int width, height, nrChanells;
    	stbi_set_flip_vertically_on_load(true);
    	unsigned char* data = stbi_load(texture_file.c_str(), &width, &height, &nrChanells, 0);
    	if (data)
    	{
    		glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_UNSIGNED_BYTE, data);
    		glGenerateMipmap(GL_TEXTURE_2D);
    	}
    	else {std::cout << "failed to load texture" << std::endl;}
    	stbi_image_free(data);
    
    	glGenBuffers(1, &ib_ID);
    	glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, ib_ID);
    	glBufferData(GL_ELEMENT_ARRAY_BUFFER, sizeof(index_buffer), index_buffer, GL_STATIC_DRAW);
    	glBindVertexArray(0);
    }
