Trying to output data which has been input by user

本文关键字：输入数据用户输出 | 更新日期: 2023-12-07

我在尝试将用户输入的数据输出到表单中时遇到问题。这是一个2块表单，我只是试图将数据保存到2个变量中，然后回显变量。但我不明白我哪里错了。感谢您的帮助。

    <?php
echo $problem = ""; 

if(isset($_POST['submit']) && $_POST['submit']=="submit"){
    if(!empty($_POST['eWeight']) && $_POST['eWeight']!=''){       
$eWeight = mysqli_real_escape_string($conn, trim($_POST['eWeight']));
    } else {
       $problem .= "Please enter a weight. <br/>";
}
if(!empty($_POST['gym']) && $_POST['gym']!=''){       
$gym = mysqli_real_escape_string($conn, trim($_POST['gym']));
    } else {
       $problem .= "Please enter time at gym. <br/>";
}

echo $eWeight, $gym;


}

?>
<?php
if($conn){
     echo "connected";
}
echo $problem;
echo $eWeight;
?>
  <form class="pure-form pure-form-stacked" name="contact_weight">
 <label for="eWeight">Enter Weight: </label> <input type="number" id="eWeight" name="eWeight" placeholder="88" required/>

 <label for="gym">Enter Time at Gym: </label> <input type="number" id="gym" name="gym" placeholder="60" required/>
<button class="submit" type="submit">Submit Form</button>
</form>

您可以执行类似的操作

<?php
echo $problem = ""; 
if(isset($_POST['submit'])){
if(!empty($_POST['eWeight']) && $_POST['eWeight']!=''){       
    $eWeight = mysqli_real_escape_string($conn, trim($_POST['eWeight']));
} else {
    $problem .= "Please enter a weight. <br/>";
}
if(!empty($_POST['gym']) && $_POST['gym']!=''){       
    $gym = mysqli_real_escape_string($conn, trim($_POST['gym']));
} else {
    $problem .= "Please enter time at gym. <br/>";
}
echo $eWeight, $gym;
}
if($conn){
  echo "connected";
}
echo $problem;
echo $eWeight;
?>
<form class="pure-form pure-form-stacked" name="contact_weight" action="" method="post">
    <label for="eWeight">Enter Weight: </label> <input type="number" id="eWeight" name="eWeight" placeholder="88" required/>        
    <label for="gym">Enter Time at Gym: </label> <input type="number" id="gym" name="gym" placeholder="60" required/>
    <button name="submit" class="submit" type="submit">Submit Form</button>
</form>
