未检测到由for定义的post [“ index”](未定义索引错误)

标签: php html

当我单击“提交”时,我会收到以下通知:

未定义索引:theIsbn0(以及theIsbn1和theIsbn2)

知道为什么吗?

<?php //<=spam
<input name="theIsbn0" ...>
?> //<=spam

edit:这是我按Ctrl + u作为第一个文本索引所看到的html代码(我添加了<?php?>,以便输入标记可以显示在我的帖子中,而实际上不在代码中):

检查 void SpawnCheckPoint() { mySlider.maxValue = gameLevel[currentLevel].maxValue; //Set the slider's Max Value to the max value of the level. float sliderMaxValue = mySlider.maxValue; float sliderWidth = slider.GetComponent<RectTransform>().sizeDelta.x; //Get the width of the Slider. float zeroValue = slider.transform.position.x - (sliderWidth / 2); //Get the leftmost corner of the slider. //Loop to Instantiate the 3 checkpoints. for (int i = 0; i < gameLevel[currentLevel].values.Length; i++) { float valueToIncrement = (gameLevel[currentLevel].values[i] / sliderMaxValue); //Get the % of the checkpoint based on the max value of the level. float newPos = (sliderWidth * valueToIncrement); //New position in screen //Instantiate the object as a child of the Slider GameObject checkpoint = Instantiate(checkPoint, new Vector3(zeroValue + newPos - xPadding, slider.transform.position.y - yPadding, slider.transform.position.z), Quaternion.identity, GameObject.FindGameObjectWithTag("Slider").transform); } } 是否存在。但使用setFactor

theIsbn{$i}"

我认为你想要(注意 if (isset($_POST["setFactor"])){ echo $_POST["theIsbn{$i}"]; ):
