Question

嗨，我有一个php mysql登录页面，一旦用户通过验证，该页面就可以正常工作（目前非常基本）。登录后，在登录页面顶部回显用户名和用户类型。

我现在很努力，要根据那里的用户类型将它们定向到不同的页面。

我添加了一个redirect.php，它根据usertyoe进行重定向。

到目前为止，这是我的文件。

您引用了$ usertype，但就代码显示而言，该点从未定义过

<script type="text/javascript">

    //declare global variables 
    var w = 600, h = 200, padding = 30, margin = 30;

    //import the .csv data
    d3.csv("WHO_familyplanningdata.csv", function(data) {
            console.log(data)});

    //create the SVG
    var svg = d3.select("body")
            .append("svg")
            .attr("width", w)
            .attr("height", h);

    //import the .csv data
    d3.csv("WHO_familyplanningdata.csv", function(data) {
            console.log(data); 

    //clean up data
    var percent = parseInt(data.percentage)

    //create rects, and add them to the SVG 
    svg.selectAll("rect")
            .data(data)
            .enter()
            .append("rect")
            .attr("x", function(d,i) {
                    return i * (w / data.length);
            }) //distributes them across the x axis 
            .attr("y", 0)
            .attr("width", (w / data.length) /2)
            .attr("height", function(d, i) { 
                    return percent;
            });

 }); //end of the data wrapping 
   </script>
