Question

我试图用购买力平价中的对应指令来重复一行超文本。这里是:

echo <tr><td><input category=“check Box” name=”。美元现值单位,“检查/研究;研究;/td><td><label> 美元现值单位单位, . </label></td></tr>

I set the name attribute of a checkbox to $currentTeam. When $currentTeam has a space character and I try to check if it s checked upon form submission, it doesn t register. When $currentTeam does not have a space character and I check the box, I m able to see if it s set using isset() upon form submission. This is strange because the same $currentTeam variable has no problem printing out just fine in the <label> for the checkbox. I m assuming it s because there something going on with the quotes and the space character.

我试图改变单一报价的用法,如两倍,但无uck。是否有任何人的想法?

当你在网页上以内容印刷时,你在<代码>上的空间是无法解释的。但是,如果你将其用作姓名、id等财产,价值将保持不变,包括拖车空间。

当你将它作为内容输出时,例如贴标签文本,将多处空间作为单一空间,而单一空间很可能在你网页上无法说明。

例如:

        $currentTeam = "team1";
        $currentTeam2 = "          team2          ";

        echo  <tr><td><input type="checkbox" name="  . $currentTeam .  " checked/></td><td><label>  . $currentTeam .  </label></td></tr> ;
        echo  <tr><td><input type="checkbox" name="  . $currentTeam2 .  " checked/></td><td><label>  . $currentTeam2 .  </label></td></tr> ;

你们在你的网页上看到了空间/空间,但如果你看一看这些内容,标签有1个空间(多片变成单一),空间仍然以检查箱名称。

当我派出时,小组2名代表的席位将保持不变。为什么没有登记:

为了确定这一点,你首先想在你网页上使用这一数值。

        $currentTeam = "team1";
        $currentTeam2 = trim("          team2          ");

        echo  <tr><td><input type="checkbox" name="  . $currentTeam .  " checked/></td><td><label>  . $currentTeam .  </label></td></tr> ;
        echo  <tr><td><input type="checkbox" name="  . $currentTeam2 .  " checked/></td><td><label>  . $currentTeam2 .  </label></td></tr> ;

2个小组的名称上没有更多的空间:
