Printing linked lists

Trying to print a linked list, but the first item is the only thing that prints. I've played around with it, and I cannot figure out whether it is my print function, or my construction of the list that is causing this.

This is my construction.

Code:

Player* open( FILE *fp ){
        int i, lines;
        char hold[ MAX_LINE ] = { 0 };
        char* token = NULL;
        const char space[] = " ";
        const char nLine[] = "\n";


        Player* head = NULL;
        char name[ MAX_NAME ] = { 0 };
        int goals;
        int assists;


        lines = countLines( fp );


/* Tokenize the strings in the file and pass them to link. */
        for( i = 0; i < lines; i++ ){
                fgets( hold, MAX_LINE, fp );


                token = strtok( hold, space );
                strcpy( name, token );


                token = strtok( NULL, space );
                goals = atoi( token );


                token = strtok( NULL, nLine );
                assists = atoi( token );


/* In the first iteration, head is NULL, thus the newly created node will be the head
 * of the list. We are returning to head because we are not passing head by reference. */
                head = link( head, name, goals, assists );


                if( token == NULL ){
                        break;
                }//endif
        }//endfr


        return head;
}//endfn


Player* link( Player* x, char name[], int goals, int assists ){
        Player* current = x; // Set our record pointer to the passed node.


/* We are calling createRecord to malloc and assign pertinant data to the node. */
        Player* newPlayer = createPlayer( name, goals, assists );


/* Now we check to see if the list is empty. */
        if( x == NULL ){
                return newPlayer;


        }else{
                while( current != NULL ){
                        current = current->next;
                }//endwh


                current = newPlayer;
        }//endel        


        return x;
}//endfn

Where createPlayer simply mallocs and assigns pertinent data to created node, then returns the pointer to the node.


This is my print function.

Code:

void printPlayers( Player* head ){

        Player* x = head;


        if( x == NULL ){
                printf("\n\nThe list is empty!\n");
        }else{
                printf("\nName       Goals      Assists");


                while( x != NULL ){
                        printf("\n%s %5d %10d", x->name, x->goals, x->assists );


                        x = x->next;
                }//endwh
        }//endel

I don't see a line where you link the "next" pointer to another node in your list. Something like "current->next = ..."

In other words, the print function is fine, and it is the contruction that is faulty.

I see, for anyone who might search for this in the future..

I changed this:

Code:

while( current != NULL ){ 
                       current = current->next; 
               }//endwh 
               current = newPlayer;

to this:

Code:

while( current->next != NULL ){ 
                       current = current->next; 
               }//endwh 
               current->next = newPlayer;

And this works.
