two ways to do.
assuming the MovieCLip is named clip
the textield is named field
you wnat to input datafromphp
1 - indirect through TellTarget and setvariable
tellTarget (clip) {
field = datafromphp;
}
not always a good option, mostly used for navigating inside MovieClips
2 - directly through SetVariable
clip.field = datafromphp;
best way to set data into MovieClips
