php - POST not sending all data -


i have screen 135 checkboxes 

<input type="checkbox" name="orders_id[] value="1"/> <input type="checkbox" name="orders_id[] value="2"/> ......... <input type="checkbox" name="orders_id[] value="135"/>

i check of checkboxes , submit, in $_post see 107 checkboxes received.

what happened missing data?

i changed post_max_size 20m did not resolve problem.

i checked on header of browser chrome developer tools. can see all 135 checked data there, in php when check $_post['orders_id'], 107 of them.

with many checkboxes, if there other inputs on form may exceeding php's max_input_vars setting. the php manual defines setting as:

how many input variables may accepted (limit applied $_get, $_post , $_cookie superglobal separately). use of directive mitigates possibility of denial of service attacks use hash collisions. if there more input variables specified directive, e_warning issued, , further input variables truncated request.

you can fix increasing setting in php.ini, or reducing number of inputs in form fit limit.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
