[omid1367 0]

سلام دوستان 

ماژول پارسا گلوبال نیوز 2.5 یکی از دوستان(آقای تهرانی ) قبلا برایم تغییراتی داده بود و سفارشی کرده بودن . این ماژول به صورت پیش فرض عکس در متن مقدمه خبر را در صفحه اصلی نمایش می دهد. که با تغییر که داده بودیم عکس را از فیلد تصویر مقدمه می آورد و نمایش میدهد

  همین mod vtem slides  حالا می خواهم برای همین ماژول اسلایدر

تغییر را بدهم و عکس تصویر متن مقدمه را نمایش دهد

 

خیلی لطف بزرگی می کنید اگر برایم اصلاحش کنید..

 

 

 است که می خواهم اصلاح شودmod vtem slides  مربوط به  helper.php این فایل
