| Promotion code | "$_POST['promotion']" |
| Mobilephone | "$_POST['mobilephone']" |

| Prescription Type | "$_POST['prescription']" |
| Single PD | "$singlepd" |

| Left PD | "$leftpd" |
| Right OD SPH | "$_POST['odsph']" |
| Left OS SPH | "$_POST['ossph']" |

| OS CYL | "$_POST['oscyl']" |
| OD AXIS | "$_POST['odaxis']" |
| OS AXIS | "$_POST['oxaxis']" |

echo mailbody;
------解决方案--------------------把形如 "$_POST['productnumber']" 的改为 {$_POST['productnumber']} 这样
