Question

我使用php JPgraph库为报告生成条形图。我想将报告导出到csv。为此我使用PHP将html写入csv。但图表不会导出到csv。它显示无法显示链接图像。没有物理图像。

report.php

<script src="js/customer_report.js"></script>
 <div><a href="#" onclick="return htmlToExcel();" /></div>
<table><tr>
<td width="50%" colspan=5 >
    <h2>Avg. by Day of Week</h2>
    <img width="90%" height="500" align="center" src="../../dhr_reports_1.php" />
</div>

</tr></table>
