I have a php file which is used to display a pdf file. The pdf file contains variables obtained from php file given below.
$areaOfCircle;
...
...
$pdf->WriteFixedPosHTML($areaOfCircle, 20, 50, 20, 50, 'auto');
And I have my Unity script here
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class SendToServer: MonoBehaviour
{
public string areOfCircle;
IEnumerator Start()
{
WWWForm form = new WWWForm();
form.AddField("areaOfCircle", areOfCircle);
UnityWebRequest www = UnityWebRequest.Get("https://localhost/sqlconnect/myFirstPhp.php");
yield return www.SendWebRequest();
if (www.isNetworkError || www.isHttpError)
{
Debug.LogError(www.error);
}
else
{
Debug.Log("Sent");
}
}
}
I am trying to send value of the string to php from Unity but I only get error message. What am I doing wrong here?
Well, you are not sending your form or any data at all.
If you want to use POST then it should rather be UnityWebRequest.Post
UnityWebRequest www = UnityWebRequest.Post("https://localhost/sqlconnect/myFirstPhp.php", form);
If your PHP however actually expects GET then you would probably rather do
UnityWebRequest www = UnityWebRequest.Get($"https://localhost/sqlconnect/myFirstPhp.php?areaOfCircle={areOfCircle}&someSecondParameter{secondParameter}");
Don't see unfortunately how exactly you are setting the $areaOfCircle variable in your PHP code ...
You can add more variables in the url separated by the & char
UnityWebRequest.Get($"https://localhost/sqlconnect/myFirstPhp.php?areaOfCircle={areaOfCircle}&secondVariable={secondValue}");
In PHP you get them with
$areaOfCirle = $_GET["areaOfCircle"];
$secondVariable = $_GET["secondVariable"];
