Chirurgia cranio-cerebrală minim invazivă
Tehnicile minim invazive impun utilizarea unei tehnologii ultramoderne. Endoscoapele operatorii de diverse tipuri, microscopul operator dedicat, neuronavigația, neuroelectrofiziologia, tehnicile avansate de anestezie, chirurgia cu pacientul treaz reprezintă armamentarium fără de care neurochirurgia prin "gaura cheii" nu ar fi posibilă. Folosind tehnicile de mai sus, tratăm un spectru larg de patologii cranio-cerebrale. www.neurohope.ro |

Buna ziua, incep prin a spune ca sunt incepator si ca nu reusesc sa sterg date din baza de date cu php...
Acesta este codul meu... cand apas pe stergere item ma redirectioneaza la http://localhost/inc...g_id=586&do=yes eu fiind in http://localhost/inc...=slider_options ... in mod normal nu ar trebuie sa imi apara primul url ci doar sa-si dea refres pagina si sa stearga itemul... mentionez ca nu intra in nici un else... din partea asta de cod...

dacă dai query-ul direct în baza de date, în phpmyadmin, merge, îți șterge? înregistrarea mă refer, nu fișierul
comentează redirectul, dă doar un echo "OK"; să vezi dacă nu cumva redirectează înainte să apuce să execute ar mai fi chestie de permisiuni sau de $con care să nu aibă drepturi sau nu găsește id-ul respectiv ca lumea.. |
