[英]Echoing only once inside a loop
i have bit of a puzzle Im unable to crack. 我有一点难题我无法破解。 I have dynamic table looping: 我有动态表循环:
echo "<table border='1' padding='2' cellspacing='0' ";
echo "<tr> <th>ID</th> <th>Producto</th> <th>Ud/Caja</th> <th>Formato</th> <th>Cajas</th> <th>Sueltas</th> <th>Total</th> </tr>";
//
while($row = mysql_fetch_array( $result )) {
// trying to a title line
if ($row['proveedor']=="Campocerrado" )
{
echo "<tr> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> </tr>";
;
;}
//
echo "<tr>";
echo "<td>" . $row['idItem'] . "</td>";
echo '<input type="hidden" name="hiddenidItem[]" id="hiddenField" value="'. $row['idItem'] .'">';
echo "<td>" . $row['producto'] . "</td>";
echo '<input type="hidden" name="hiddenProducto[]" id="hiddenField" value="'. $row['producto'] .'">';
echo '<input type="hidden" name="proveedor[]" id="lastValue" value="'. $row['proveedor'] .'">';
echo "<td>" . $row['ud/caja'] . "</td>";
echo '<input type="hidden" name="ud/caja[]" id="hiddenField" value="'. $row['ud/caja'] .'">';
echo "<td>" . $row['formato'] . "</td>";
echo '<input type="hidden" name="formato[]" id="hiddenField" value="'. $row['formato'] .'">';
echo '<td><input type="number" name="cajas[]" id="cajas[]" value=""></td>';
echo '<td><input type="number" name="sueltas[]" id="sueltas[]" value=""></td>';
echo '<td><input type="number" name="total[]" id="total" value=""></td>';
echo '<input type="hidden" name="lastValue[]" id="lastValue" value="'. $row['total'] .'">';
echo '<input type="hidden" name="proveedor[]" id="lastValue" value="'. $row['proveedor'] .'">';
echo "</tr>";
}
echo "</table>";
echo "<br>";
The part I'm not able to figure out is this: 我无法弄清楚的部分是:
if ($row['proveedor']=="Campocerrado" )
{
echo "<tr> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> </tr>";
;
;}
What I'm trying to do is run the loop until it encounters a specific $row
to display the html for the row once. 我正在尝试做的是运行循环,直到它遇到一个特定的$row
来显示$row
的html一次。
So far, Im getting this : 到目前为止,我得到了这个:
But I need something like this to be more precise: 但我需要这样的东西更精确:
In the pure simplest form of an answer, use a token. 在纯粹最简单的答案形式中,使用令牌。
$tokenhit = false;
if (!$tokenhit && $row['proveedor']=="Campocerrado" ) {
echo "<tr> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th>
<th>TEST</th> <th>TEST</th> <th>TEST</th> </tr>";
$tokenhit = true;
}
But i am not sure this answers your true question or not. 但我不确定这是否回答了你的真实问题。
set a flag to indicate that you've already output your extra row: 设置一个标志,表示您已经输出了额外的行:
$show_extra_row = true;
while(...) {
if (($row['proveedor']=="Campocerrado" ) && $show_extra_row) {
$show_extra_row = false;
echo ...
}
}
After it's displayed for the first time, the flag becomes false and the extra row will never be output again. 在第一次显示之后,标志变为false,并且永远不会再输出额外的行。
you can have a temporary variable to check if the condition already met before. 您可以使用临时变量来检查之前是否已满足条件。
$firstTime = true;
while($row = mysql_fetch_array( $result )) {
// trying to a title line
if ($firstTime && $row['proveedor']=="Campocerrado" )
{
echo "<tr> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th> <th>TEST</th<th>TEST</th> <th>TEST</th> </tr>";
$firstTime = false;
}
...
}
