Php身份不明的索引

-1

你能告訴我爲什麼說actual_quote和海報是不明身份的索引嗎？我一直在爲此掙扎一個小時。Php身份不明的索引

繼承人在那裏，他們得到的值

<form name = "quoted" form action = "question.php" method="get"> 
    <input id = "poster" type="text" name="poster" required="required" placeholder = "Credited Individual.">  
    <br> 
    <textarea class = "actual_quote" name = "actual_quote" required="required" placeholder = "Write the question here!"></textarea> 
    <br><br><br> 

    <div class = "checkboxes" required="required"> 
     <h3 style = "margin-top:-20px;">Please select one catagory that the quote falls into.</h3> 
     <label for="x"><input type="radio" name="x" value="stupid" id = "x" checked="checked" action = "stupid.php" /><span>stupid</span></label> 
     <br> 
     <label for="x"><input type="radio" name="x" value="stupider" id = "x" action = "stupider.php" /><span>stupider</span></label> 
     <br> 
     <label for="x"><input type="radio" name="x" value="stupidest" id = "x" action = "stupidest.php" /><span>stupidest</span></label> 
    </div> 

    <input id = "submit1" type="submit"><br> 
</form> 
<div class="wrapper"> 
<div class="submissions"> 
    <div class="logo-logo"><h2>Quotr.</h2> 
<div class="checkboxes"><?= !empty($_GET['x']) ? $_GET['x'] : '' ?> 
</div> 

    </div>

然後這裏的地方PHP是抓住了值和網頁上顯示它們的形式，在都顯示此錯誤

Notice: Undefined index: actual_quote in the index of the file on line 47 
Call Stack 
Time Memory Function 
1 0.0004 254200 {main}()

，反之亦然海報

<div class="top-submit"><?php echo '&#8220;' . (!empty($_GET['actual_quote']) ? $_GET['actual_quote'] : '') . '&#8221;'; $actual_quote = isset($_GET['actual_quote']) ?: false;?> 
    </div> 
    <div class="poster"><?php echo "-" . (!empty($_GET['poster']) ? $_GET['poster'] :''); $poster = $_GET['poster']; $poster = isset($_GET['poster']) ?: false;?> 
    <div class = "like"> 
    <a href = "javascript:countClicksLike();" class = "btn btn-large" style = "color:green;">Like</a> 
    <p id = "like" style = "color:green;">0</p> 
    </div> 
    <div class = "dislike"> 
    <a href = "javascript:countClicks();" class = "btn btn-large" style = "float:right; color:red;">Dislike</a> 
    <p id = "dis" style = "color:red;">0</p> 
    </div> 
    </div>

請幫忙！我很難過。由於提前， -Connor

首先檢查isset http://in2.php.net/isset然後檢查它是否爲空 – Prashank

是第二個文件question.php？ – anthonygore

按原樣運行此代碼不會產生該錯誤。你能提供完整的代碼嗎？此外，您的表單中有無效的屬性。表單標籤中的「form」，輸入標籤中的「action」無效，什麼也不做。你能在這裏進一步解釋你的意圖嗎？ – anthonygore

<?php $actual_quote = (isset($_GET['actual_quote']) ? $_GET['actual_quote'] : ''); ?> 
<div class="top-submit"><?php echo '&#8220;' . $actual_quote . '&#8221;'; ?>

更改爲空（）函數調用isset（）函數。
