Given the polar coordinate equation of line $l$ as $\sqrt {2}ρ\cos (θ+ \dfrac {π}{4})=-1$, and the parametric equation of curve $C$ as $ \begin{cases} x=t \\ y=t^{2} \end{cases}(t$ is the parameter$)$, establish a rectangular coordinate system with the pole as the origin and the polar axis as the positive $x$-axis direction. Point $M( \dfrac {1}{2}- \dfrac { \sqrt {5}}{2}, \dfrac {1}{2}- \dfrac { \sqrt {5}}{2})$, and line $l$ intersects curve $C$ at points $A$ and $B$.
(I) Find the ordinary equations of line $l$ and curve $C$;
(II) Calculate the value of $|MA|^{2} \cdot |MB|^{2}$.
