OpenGL Texture on height map

i’m working on the rendering of an height map terrain and everything works fine except the texture. I have to stretch a jpg file over the whole terrain (using GLM) but it doesn’t work! This is part of my code, just to be clear (Terreain.cpp):

GLfloat height, width;

int CreateTerrain::getTextureID(){
GLuint textID = glmLoadTexture(“terrain.png”,GL_TRUE, GL_TRUE, GL_TRUE, GL_TRUE,&width, &height);
return textID;
}

float* CreateTerrain::getTexture(){
int j = 0;
float iF = (width/mapCols)/width;
float jF = (height/mapRows)/height;
for ( int row = 0; row < mapRows; row++ ) {
for ( int col = 0; col < mapCols; col++ ) {
terrainTexture[j++] = (float) rowiF;
terrainTexture[j++] = (float) col
jF;
}
}
return terrainTexture;
}
and this is the file main.cpp:

GLuint textID = terrain.getTextureID();
float* texture = terrain.getTexture();

void RenderTerrain(){
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D,textID);
glEnable(GL_COLOR_MATERIAL);
glTranslatef( -(MAP_COLS*CELL_SIZE)/2, 0, -(MAP_ROWS*CELL_SIZE)/2);
glEnableClientState( GL_VERTEX_ARRAY );
glEnableClientState(GL_NORMAL_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
    glVertexPointer( 3, GL_FLOAT, 0, vertices  );
    glNormalPointer(GL_FLOAT, 0, normals );
    glTexCoordPointer(2,GL_FLOAT,0,texture);
    for ( int row = 0; row &lt; MAP_ROWS - 1; row++ ) {
        int i = 0;
        for ( int col = 0; col &lt; MAP_COLS; col++ ) {
            indices[i++] = col + (row * MAP_COLS);
            indices[i++] = col + (row * MAP_COLS) + MAP_COLS;
        }
        glPushMatrix(); 
            glDrawElements( GL_TRIANGLE_STRIP,  i, GL_UNSIGNED_INT, indices );
        glPopMatrix();
    }
glDisableClientState( GL_VERTEX_ARRAY );
glDisableClientState(GL_NORMAL_ARRAY);
glDisableClientState (GL_TEXTURE_COORD_ARRAY);}

I read a lot of tutorial but i didn’t find the solution. Every tip is really appreciated! Thanks in advance!

I don’t know whether you’ve just made a copy-paste error in this post, but you never assign a value to _textureId (only to textID)

yes now i fixed the error… but i can only see white terrain without my jpg texture!
